Right now

• Many results from the Tevatron (top, precision tests,…)• Neutrino mass and mixing have been established• Beautiful physics is coming from the SLAC and KEK B

factories• Charming physics is coming from CLEO• Proton structure from HERA• RHIC physics• Lattice calculations have achieved impressive precision• Cosmology and astrophysics have become extremely

interesting, with experiments in space, on the ground, and underground

• The start of the LHC era

Top

Despite all expectations, no new physics yet

?

Neutrinos

•Majorana vs Dirac

•Absolute scale of masses

•CP violation

•Normal or inverted spectrum

•LSND anomaly

(Lepton Flavor Violation)

QCD

Challenging theoretically and experimentally

Spin physics (angular momentum)

Quark-gluon plasma

Pentaquarks ?

Possible Accelerator Developments

• Luminosity upgrade for the LHC, termed the SLHC, aiming at a luminosity up to 10^35 cm-2 s-1.

• Energy upgrade for the LHC, termed the DLHC• Linear colliders form another very prominent class of

opportunities, that would continue the exploration of the high-energy frontier initiated by the LHC (500-800 GeV).

• Another possible option is a neutrino facility, which might consist of a super beam and/or beta beam or a neutrino factory leading eventually to muon colliders (Information provided by neutrino oscillation experiments).

• Multi-TeV e+e− collider CLIC.

Possible LHC Outcomes

(a) New physics beyond the Standard Model; or

(b) A Standard-Model-like Higgs and no physics beyond the Standard Model.

Astroparticles

• Quantum gravity.• Dark matter and dark energy (95% of Universe beyond

SM: 70% DE, 25% DM)• Gravitational waves.• Cosmic rays: observation of the GZK cutoff• Neutrino astronomy Amanda, Antares,…• Baryon asymmetry of the Universe (leptogenesis,…)• Gamma ray bursts• Vacuum birefrigence (axions,…)

Strings

• String theory is a consistent theory of

quantum gravity.

• String theory incorporates the standard

model.

• String theory has not explained yet either

the big-bang singularity, or the particular

structure of the standard model.

Thanks for your nice work at this Conference

We hope to see all of you here once again in the near future.
