${\mathrm{B}}_{(\mathrm{s})}^0\to {\mu }^{+}{\mu }^{-}$ rare decays at LHC

Abstract

The ATLAS, CMS, and LHCb collaborations have leveraged data from proton-proton collisions at the Large Hadron Collider (LHC) to advance our understanding of fundamental particles and their interactions. These collaborative efforts underscore the significance of integrating datasets across different runs and energy levels, yielding insights that contribute to the ongoing measurements of the ${\mathrm{B}}_{(\mathrm{s})}^0\to {\mu }^{+}{\mu }^{-}$ decay branching fractions and ${\mathrm{B}}_{\mathrm{s}}^0\to {\mu }^{+}{\mu }^{-}$ effective lifetime.
