Rare decays at LHCb

Abstract

05 - LHCbRare loop-induced decays are sensitive to New Physics in many Standard Model extensions. In this paper we discuss the reconstruction of the radiative penguin decays ${mathrm{B^0}} rightarrow {mathrm{K}^{*0}}gamma$, ${mathrm{B^0_{mathrm{s}}}} rightarrow phi gamma$, ${mathrm{B^0}} rightarrow omega gamma$, the electroweak penguin decay ${mathrm{B^0}}r ightarrow {mathrm{K}^{*0}}mu^+mu^-$, the gluonic penguin decays ${mathrm{B^0}} rightarrow {mathrm{K^0_S}}phi$, ${mathrm{B^0_{mathrm{s}}}}r ightarrow phi phi$ and the decay ${mathrm{B^0_{mathrm{s}}}} rightarrow mu^+ mu^-$ at LHCb. The selection criteria, evaluated efficiencies, expected annual yields and $mathcal{B}/mathcal{S}$ estimates are presented
