  1. Highlights of theEPS 2011 conference(Grenoble, July 2011) Evgueni Goudzovski (University of Birmingham) • A personal selection of new results: • Higgs & new physics searches at hadron colliders; • Flavour physics at the LHC; • Lepton flavour violation: MEG; • Neutrino oscillation measurements. Birmingham PP seminar 5 October 2011

  2. Higgs & new physics searchesat hadron colliders

  3. Tevatron Higgs limits ~8fb–1 • Tevatron prospects: • large improvements in sensitivity; • Next spring: results basedon the full 10fb–1 sample. Presented by Eric James

  4. SM Higgs cross-sections SM Higgs at LHC Sensitivities (ATLAS) BR Low mass: Hbb, , . Intermediate mass: HWWll. High mass: HZZll, llqq, llll.

  5. H Examples (ATLAS) Presented by Dave Charlton HZZ4l

  6. Presented by William Murray The LHC limits: July 2011 ? ? ATLAS+CMS combination is complex, and was not presented at EPS 2011. ~(155-206; 270-450) GeV excluded. Limits improved/revised at LP11!

  7. SM & searhes at the LHC

  8. LHCb: B0K*+–

  9. LHCb data taking (by end of July) Luminosity levelling delivers constant operation at L~3x1032/cm2/s

  10. B0K*+– (FCNC: bs) BR~10–6 B-factories hinted apositive AFB for all q2…

  11. LHCb analysis K*K J/ World’slargest sample (2S)

  12. Forward-backward asymmetry A textbook confirmation of the SM prediction… …presented by M.Patel (Imperial College)

  13. LHC: Bs+–

  14. The “golden mode”: Bs+–

  15. Bs+– Presented by Guy Wilkinson

  16. Bs+– Presented by Guy Wilkinson

  17. LHCb analysis 300 pb–1 Boosted decision tree analysis (similar to PLB 699(2011)330)

  18. LHCb preliminary limit 300 pb–1

  19. CMS analysis 1.14 fb–1 (at least one ||>1.4) (both  ||<1.4)

  20. BR(Bs+–) combination 27 July 2011 90%CL 95%CL Presented by Guy Wilkinson

  21. Lepton Flavour Violation:e @ MEG exp’t

  22. Presented by Toshinori Mori-san The MEG experiment • World’s most intensivemuon beam @ PSI; • Thin  stoppingtarget (polyethylene); • Spectrometer+ LXe calirimeter. Signal: e (back-to-back). Background: e (the Michel decay). Accidental BKG is dominant.

  23. Presented by Toshinori Mori-san 2010 data analysis

  24. Presented by Toshinori Mori-san Updated MEG results Likelihood profiles The hint for new physicsseen in 2009 datahas disappeared ~10–13 sensitivityexpected with the2011+12 data set

  25. Neutrino physics

  26. First T2K appearance results Electron neutrino appearance in  beam: P(e) = sin2(213)sin223sin2(m2atmL/4E) (with 2% of the T2K expected flux) First indicationof non-zero 13

  27. eappearance @ MINOS Electron neutrino appearance in  beam: P(e) = sin2(213)sin223sin2(m2atmL/4E)

  28. Three-flavour global analysis Presented by S.Schoenert Double Choozexpected sensitivity Reactor e (~1MeV) disappearanceexperiment Near-detectoroperational • 3 indication of non-zero 13; • T2K to continue data acquisition soon; • New generation of reactor experiments with near&far detectors starting (Daya Bay, Double Chooz, RENO)

  29. Disappearance: T2K & MINOS Muon neutrino disappearance:P() = 1 – sin2(213)sin2(m232L/4E) MINOS@Fermilab (8x1020 POT) MINOS:
