\(b \rightarrow s\ell ^+ \ell ^-\) Transitions at LHCb

Rare 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

Electroweak Physics at LHCb

The LHCb forward acceptance covers a range of rapidities not accessible by the other LHC experiments, allowing for complementary measurements. We report recent measurements of electroweak boson production, either inclusive, or in association with a jet or a D meson.

γ measurements at LHCb

The LHCb collaboration has studied various promising ways to determine the Unitarity Triangle angle γ. Three complementary methods will be considered. The potential of the B → DK(∗) decays has been studied by employing the combined Gronau-London-Wyler (GLW) and the Atwood-Dunietz-Soni (ADS) methods, making use of a large sample of simulated data. γ can also be extracted with a time-dependent an...

Rare decays at LHCb

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.
