Synergy between Energy and Luminosity Frontiers (Summary) 1 Y.Sakai (KEK) 2010: Great Year ! 2 LHC: start taking physics data at TeV Luminosity Frontier: SuperKEKB: June; funded ~$100M Dec; Fully approved for FY2011 by Govmnt (will be a final decision after Diet approval) Upgrade(construction) work started ! SuperB: Dec; funded ~20M euro for 2010 by Italian Govnmt ~270M euro for 5 years Energy Frontier: Current Understanding 3 Standard Model 6 quarks & 6 leptons 3 Bosons (Forces) Higgs (mass) Quark mixing CP Violation mixing/mass CPV in mixing New Physics NP particles NP flavor structure (Lepton flavor V.)

CP violating effects in the B sector are O(1) rather than O(10 -3 ) as in the kaon system. 2008: 28 29 WA, PDG08 B rec = J/K S + J/K L still ~20% of room for NP: more precise measurements needed Success of KM model 30 WMAP Too small by 10 orders of magnitude in the SM The most compelling hint for new physics in the weak interaction is the BAU Search for New CPV source Latest tension in between tree and penguin B J/K (b c) B K, K (b s) 31 Sensitivity to new physics from charged Higgs The B meson decay constant, determined by the B wavefunction at the origin H + Search: B + + (Decays with Large Missing Energy) (|V ub | taken from indep. measurements.) 32 Why measuring is non-trivial (4S) B-B- B+B+ e+e+ e B + + , + e + e B-XB-X The experimental signature is rather difficult: B decays to a single charged track + nothing 33 Can be measured only by B-Factory !
