Prospects for CP violation and rare decays at ATLAS and CMS.

The LHC experiments will perform sensitive tests of physics beyond the Standard Model (BSM). Investigation of B hadrons decays represents an alternative approach to direct BSM searches. ATLAS and CMS concentrate on B decays that can be registered by di-muon signature already at first trigger level....

description The LHC experiments will perform sensitive tests of physics beyond the Standard Model (BSM). Investigation of B hadrons decays represents an alternative approach to direct BSM searches. ATLAS and CMS concentrate on B decays that can be registered by di-muon signature already at first trigger level. B-hadrons decaying to Jpsi-mumu will statistically dominate B-physics analysis allowing high precision measurements, in particular a test of BSM effects in the CP violation of Bs-Jpsiphi. In rare B decays ATLAS and CMS concentrate on a family of semi-muonic exclusive channels, b-smumu, and on purely muonic decay Bs-mumu. In 3 years at luminosity several units of 1033 cm-2 s-1, corresponding to 30 fb-1, each of these two experiments can measure the Bs-mumu signal with the 3 sigma significance, supposing SM value for a decay probability.

ATLAS and CMS concentrate on B decays that can be registered by a di-muon signature. B-hadrons decaying to J/psi(mumu) will statistically dominate B-physics analyses allowing high precision measurements, in particular a test of BSM effects in the CP violation of Bs-Jpsiphi. In the so-called rare B-decay sector, ATLAS and CMS will concentrate on a family of semi-muonic exclusive channels, b - s mumu and on the purely muonic decay Bs - mumu. After three years of LHC running at a luminosity of a few times 1033 cm-2 s-1 (corresponding to 30 fb-1), each of these two experiments can measure the Bs-mumu signal with 3 sigma significance, assuming the Standard Model (SM) value for the decay probability.arXiv:0810.3618ATL-PHYS-PROC-2008-059ATL-COM-PHYS-2008-180oai:cds.cern.ch:11338262008-10-13
