• Higgs boson mass measured to ~0.2% precision (fixes the SM prediction!)

• Higgs boson coupling strengths measured to ~10-25% precision • Branching fraction to invisible constrained to < 25-30% • First studies of spin, CP eigenstate/admixtures, differential

distributions, all compatible with the SM

• Coupling to fermions not fully established yet in LHC run-1

• Notably coupling to top and bottom quarks not directly observed in LHC run-1

• Precision on the (inclusive) Higgs coupling strength modifiers leaves room for new physics (BSM) at ~O(TeV) • BSM effects may be enhanced at high

transverse momentum, in tails of distributions

• Great progress in LHC run-2! • Will discuss combined measurements of SM

Higgs boson properties based on 36-80 fb-1 of data collected at a centre-of-mass energy of 13 TeV

So, are we done yet?

1.2 Coupling Measurements 9

fermions, such as top partners, and colored scalars can contribute to H ! gg and H ! ��, while electricallycharged scalars and heavy leptons can contribute to H ! ��. Below we examine some representative models,in order to get a feel for the size of the possible e↵ects.

In Little Higgs models with T parity, the couplings scale with the top partner mass, MT , and assuming theHiggs couplings to Standard Model particles are not changed, the loop induced couplings are [32],

In this scenario the production rate from gluon fusion is suppressed, while the width into �� in increased.Adding a vector-like SU(2) doublet of heavy leptons does not change the gg ! H production rate, but cangive an enhancement in � of order ⇠ 20%, although large Yukawa couplings are required [33].

Colored scalars, such as the stop particle in the MSSM, also contribute to both g and � . If we considertwo charge- 2

3scalars as in the MSSM, then for a stop squark much heavier than the Higgs boson [32],

where again �� ' �0.28�g. Here Xt =| At �µ cot� | is the stop mixing parameter. If Xt = 0, the Higgscouplings to gluons is always increased and the coupling to photons decreased. If the stops are light, andthe mixing is small, large enhancements are possible. In the MSSM, there are other loop contributions tothe H�� and Hgg couplings which have been extensively studied. Enhancements in the H ! �� couplingcan be obtained with light staus and large mixing, with e↵ects on the order of ⇠ 25% [34].

In Table 1-8, we summarize the generic size of coupling modifications when the scale of new physics isconsistently taken to be M ⇠ 1 TeV.

1.2.3 Theory Uncertainties on LHC Higgs Production

The uncertainty on Higgs production has been studied by the LHC Higgs cross section working group for thevarious channels and is summarized in Table 1-9 [35]. These uncertainties must be included in extractions ofthe scale factors i from LHC data. The error includes factorization/renormalization scale uncertainty andthe correlated uncertainty from ↵s and the PDF choice, which are added linearly. The scale uncertainty onthe gluon fusion rate is ⇠ ±10%, which can potentially be significantly reduced with the inclusion of recent

Methodology

10

Constructing probability models

• Given a set of measurements and a hypothesis, a likelihood function is defined as the probability of the data under this hypothesis, formulated as a probability density function

• At the LHC, templates typically are derived from histograms with each bin effectively being a Poisson counting experiment

• Clean event categories allow disentangling production modes, leading to low correlations between measurements • Anti-correlation between ggF and VBF production due to ggF contamination in VBF enriched categories

• Systematic and statistical uncertainties of similar size in some channels, with sizeable (but conservative) theoretical uncertainties on modelling of signal and background processes

• O(10%) precision on ggF cross section • State-of-the-art theory prediction (N3LO QCD+NLO EW [JHEP 1605 (2016) 058]), has ~5% uncertainty

BSM interpretation of coupling measurements

29

2HDM and hMSSM• Interpret Higgs coupling strength results in terms of BSM model parameters

• Complementary to the limits obtained from direct searches for new physics • Consider different types of 2HDMs and the hMSSM under certain assumptions

• Higgs boson identified as the light CP-even neutral scalar, exhibiting only SM production and decay modes

• Neglect corrections of the ggF production and diphoton decay rates from SUSY partners as well as effects breaking the universality of down-type fermion couplings

Table 5: Couplings of the light Higgs boson h to weak vector bosons (V ), up-type quarks (u), down-type quarks(d), and charged leptons (`), expressed as ratios to the corresponding SM predictions in 2HDMs of various types.

Table 5 expresses the scale factors for the light Higgs boson couplings, [V , u, d, `], in terms of ↵ andtan � for each of the four types of 2HDMs [69]. The coupling scale factors are denoted V for the W andZ bosons, u for up-type quarks, d for down-type quarks, and ` for charged leptons.

The Higgs boson rate measurements in di↵erent production and decay modes are interpreted in each ofthese four types of 2HDMs, taking the observed Higgs boson to be the light CP-even neutral Higgs bosonh. This is done by rescaling the production and decay rates as functions of the coupling scale factors[V , u, d, `]. The measurements of these coupling scale factors or ratios of them [10], taking the sameproduction and decay modes as in the SM, are given in Models 3–5 of Table 1. These coupling scalefactors are in turn expressed as a function of the underlying parameters, the two angles � and ↵, usingthe relations shown in Table 5. Here the decay modes are taken to be the same as those of the SM Higgsboson.

After rescaling by the couplings, the predictions agree with those obtained using the SUSHI 1.1.1 [70]and 2HDMC 1.5.1 [71] programs, which calculate Higgs boson production and decay rates respectivelyin two-Higgs-doublet models. The rescaled gluon fusion (ggF) rate agrees with the SUSHI prediction tobetter than a percent, and the rescaled decay rates show a similar level of agreement. The cross sectionfor bbh associated production is calculated using SUSHI and included as a correction that scales with thesquare of the Yukawa coupling to the b-quark, assuming that it produces di↵erential distributions that arethe same as those in ggF. The correction is a small fraction of the total production rate for the regions ofparameter space where the data would be compatible with the SM at the 95% CL.

The two parameters of interest correspond to the quantities cos(��↵) and tan �. The 2HDM possesses an“alignment limit” at cos(��↵) = 0 [66] in which all the Higgs boson couplings approach their respectiveSM values. The 2HDM also allows for limits on the magnitudes of the various couplings that are similarto the SM values, but with a negative relative sign of the couplings to particular types of fermions. Theselimits appear in the regions where cos(� + ↵) = 0, as shown in Table 5. For example, in the Type IImodel the region where cos(� + ↵) = 0, corresponding to the sign change ↵ ! �↵, has a “wrong-signYukawa limit” [72, 73] with couplings similar to the SM values except for a negative coupling to down-type quarks. The case for the Flipped model is similar, but with a negative coupling to both the leptonsand down-type quarks. An analogous “symmetric limit” [73] appears in the Lepton-specific model.

Figure 5 shows the regions of the [cos(� � ↵), tan �] plane that are excluded at a CL of at least 95% foreach of the four types of 2HDMs, overlaid with the exclusion limits expected for the SM Higgs sector.The ↵ and � parameters are taken to satisfy 0 � ⇡/2 and 0 ��↵ ⇡ without loss of generality. Theobserved and expected exclusion regions in cos(� � ↵) depend on the particular functional dependenceof the couplings on � and ↵, which are di↵erent for the down-type quarks and leptons in each of thefour types of 2HDMs, as shown in Table 5. There is a physical boundary V 1 in all four 2HDMtypes, to which the profile likelihood ratio is restricted. The data are consistent with the alignment limit

and mZ is the mass of the Z boson.

To test the hMSSM model, the measured production and decay rates are expressed in terms of the cor-responding coupling scale factors for vector bosons (V ), up-type fermions (u), and down-type fermions(d). The observed Higgs boson is taken to be the light CP-even neutral Higgs boson h. In the hMSSM,it is assumed to have the same production and decay modes as in the SM. For comparison, Model 4 ofTable 1 lists the measurements of ratios of the coupling scale factors [V , u, d] [10]. The coupling scalefactors are in turn cast in terms of mA and tan � using Eq. (18). A correction is applied for bbh associatedproduction as a function of the b-quark Yukawa coupling as described in Section 7.

Loop corrections from stops in ggF production, which can decrease the rate by 10–15% for a lightstop [84], and in diphoton decays are neglected. Light tau sleptons (staus) with large mixing couldenhance the diphoton rate by up to 30% at tan � = 50 [84], and charginos could modify the diphoton rateby up to 20% [74, 75, 77, 85]; these e↵ects are not included in the hMSSM model.

Additional corrections in the MSSM would break the universality of down-type fermion couplings, res-ulting for example in b , ⌧. These are generally sub-dominant e↵ects [81–83] and are not included.The MSSM includes other possibilities such as Higgs boson decays to supersymmetric particles, decaysof heavy Higgs bosons to lighter ones [86], and e↵ects from light supersymmetric particles [84], whichare not investigated here. This model is therefore not fully general but serves as a useful benchmark,particularly if no direct observation of supersymmetry is made.

Contours of the two-dimensional likelihood in the [mA, tan �] plane for the hMSSM model are shown inFigure 6. The data are consistent with the SM decoupling limit at large mA. The observed (expected)lower limit at the 95% CL on the CP-odd Higgs boson mass is at least mA > 370 GeV (310 GeV) for1 tan � 50, increasing to 440 GeV (330 GeV) at tan � = 1. The observed limit is stronger thanexpected because the measured rates in the h! �� [21] (expected to be dominated by a W boson loop inthe SM) and h ! ZZ⇤ ! 4` [22] channels are higher than predicted by the SM, but the hMSSM modelhas a physical boundary V 1 so the vector-boson coupling cannot be larger than the SM value. Thephysical boundary is accounted for by computing the profile likelihood ratio with respect to the maximumlikelihood obtained within the physical region of the parameter space, mA > 0 and tan � > 0. The region1 tan � 50 is shown; at significantly smaller or larger values of tan �, the hMSSM model is not agood approximation of the MSSM. For tan � < 1, the couplings to SM particles receive potentially largecorrections related to the top sector that have not been included [87].

Light tau sleptons (staus) with large mixing couldenhance the diphoton rate by up to 30% at tan � = 50 [84], and charginos could modify the diphoton rateby up to 20% [74, 75, 77, 85]; these e↵ects are not included in the hMSSM model.

Additional corrections in the MSSM would break the universality of down-type fermion couplings, res-ulting for example in b , ⌧. These are generally sub-dominant e↵ects [81–83] and are not included.The MSSM includes other possibilities such as Higgs boson decays to supersymmetric particles, decaysof heavy Higgs bosons to lighter ones [86], and e↵ects from light supersymmetric particles [84], whichare not investigated here. This model is therefore not fully general but serves as a useful benchmark,particularly if no direct observation of supersymmetry is made.

Contours of the two-dimensional likelihood in the [mA, tan �] plane for the hMSSM model are shown inFigure 6. The data are consistent with the SM decoupling limit at large mA. The observed (expected)lower limit at the 95% CL on the CP-odd Higgs boson mass is at least mA > 370 GeV (310 GeV) for1 tan � 50, increasing to 440 GeV (330 GeV) at tan � = 1. The observed limit is stronger thanexpected because the measured rates in the h! �� [21] (expected to be dominated by a W boson loop inthe SM) and h ! ZZ⇤ ! 4` [22] channels are higher than predicted by the SM, but the hMSSM modelhas a physical boundary V 1 so the vector-boson coupling cannot be larger than the SM value. Thephysical boundary is accounted for by computing the profile likelihood ratio with respect to the maximumlikelihood obtained within the physical region of the parameter space, mA > 0 and tan � > 0. The region1 tan � 50 is shown; at significantly smaller or larger values of tan �, the hMSSM model is not agood approximation of the MSSM. For tan � < 1, the couplings to SM particles receive potentially largecorrections related to the top sector that have not been included [87].

2HDM and hMSSM• Interpret Higgs coupling strength results in terms of BSM model parameters

• Complementary to the limits obtained from direct searches for new physics • Consider different types of 2HDMs and the hMSSM under certain assumptions

• Higgs boson identified as the light CP-even neutral scalar, exhibiting only SM production and decay modes

• Neglect corrections of the ggF production and diphoton decay rates from SUSY partners as well as effects breaking the universality of down-type fermion couplings

• Define common fiducial volume to extrapolate cross sections to total phase space

• Correction for acceptence and branching fractions using bin-by-bin factors derived from simulation assuming SM production mode fraction within uncertainties

• Select common bin boundaries for observables of interest

• Updated 80 fb-1 results of individual channels available already!

• Other channels more challenging due to non-reconstructable Higgs candidate or reliance on multivariate techniques

• EFT interpretations (limits on Wilson coefficients): interpolate between samples for different values of Wilson coefficients for each bin of the distributions
