Rare decays at LHCb
نویسنده
چکیده
Rare decays of B and D mesons are sensitive to the presence of physics beyond the Standard Model as they are mediated by loop diagrams. New physics can be probed by measuring unexpectedly high branching ratios, CP, isospin and forward backward asymmetries and other angular observables. Recent results obtained by the LHCb experiment in this field are presented in this document.

The high level trigger for rare decays at LHCb
The LHCb experiment is dedicated to the study of CP violation and rare B decays. A trigger system is developed to filter these decays from the LHC background environment. An overview of the LHCb trigger strategy is given in this paper as well as an illustration on how the trigger selects the rare decays B d → K * 0 + − and B s → and their control samples, which are used to parametrize possible ...
متن کاملRare B decays at LHCb
Rare loop-induced decays are sensitive to New Physics in many Standard Model extensions. In this paper we discuss the potential of the LHCb experiment to very rare Bs → μ μ decays, radiative penguin b → sγ decays and electroweak penguin b → sll decays. The experimental strategies and the expected sensitivities are presented. PACS. PACS-key 14.40.Nd – PACS-key 12.60.-i
متن کاملRare charm decays at LHCb
Flavour-changing neutral current decays such as c → ul + l − are highly suppressed in the Standard Model, but may be enhanced by New Physics. The latest searches for such decays at LHCb based on 1.0 fb −1 of data collected in 2011 are presented in this document. Two decays, 2-body
متن کاملRare leptonic and semileptonic b-hadron decays and tests of lepton flavour universality at LHCb
Rare decays of heavy-flavoured particles provide an ideal laboratory to look for deviations from the Standard Model, and explore energy regimes beyond the LHC reach. Decays proceeding via electroweak penguin diagrams are excellent probes to search for New Physics, and b→ s`+`− processes are particularly interesting since they give access to many observables such as branching fractions, asymmetr...
