34. Prospects for K+ ->pi+ nu nu observation at CERN in NA62

Ferdinand Hahn (CERN)

04/12/2014, 16:35

The rare decays K+ ->pi+ nu nu are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness. The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%. Part of the experimental apparatus has been commissioned during a technical run...

19. Study of B -> K pi pi gamma decays

Alessandro Pilloni (Sapienza U.)

In b -> s gamma transitions, the standard model predicts that B0 (antiB0) decays are related predominantly to the presence of right (left) handed photons in the final state. Therefore, the mixing-induced CP asymmetry in B -> fCP decays, where fCP is a CP eigenstate, is expected to be small. This prediction may be altered by new-physics (NP) processes in which opposite helicity...

111. B-physics with ATLAS and CMS

Nuno Viegas Guerreiro Leonardo (Purdue University (US))

04/12/2014, 17:30

The large production rates of heavy flavoured particles at the LHC provide excellent opportunities to test the standard model and probe for new physics effects. A review of selected recent measurements by ATLAS and CMS based on LHC Run I data is presented, along with prospects for coming LHC runs.

17. Study of CP violation effects in the charmless hadronic decay B -> Ks pi+ pi0

Dr Thomas Edward Latham (University of Warwick (GB))

04/12/2014, 18:05

We report a Dalitz plot analysis of the charmless hadronic decays of charged B mesons to the final state Ks pi+ pi0 using the full BaBar dataset of 471 million BBbar events collected at the Upsilon(4S) resonance. We observe an excess of signal events and measure the branching fractions and CP asymmetries, for the different resonant decay modes and inclusively.

75. Study of KS semileptonic decays and CPT tests with the KLOE detector

Daria Kaminska

04/12/2014, 18:30

Study of semileptonic decays of neutral kaons allows to perform a test of discrete symmetries, as well as basic principles of the Standard Model. In this presentation a general review on dependency between charge asymmetry constructed for semileptonic decays of short- and long-lived kaons and CPT symmetry is given. The current status of determination of charge asymmetry for short-lived kaon,...

35. Precision tests of the Standard Model with kaon decays at CERN

Karim Massri (University of Birmingham (GB))

04/12/2014, 18:55

Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged kaon at a 0.4% precision constrains the parameter space of new physics models with extended Higgs sector, a fourth generation of quarks and leptons or sterile neutrinos. Searches for heavy neutrino...
