Angular analysis and branching ratio measurement of the decay ${\rm B}^0 \rightarrow {\rm K}^{*0} \mu^+ \mu^-$

The angular distributions and the differential branching fraction of the decay ${\rm B}^{0} \rightarrow {\rm K}^{*0} \mu^{+} \mu^{-}$ are studied using an integrated luminosity of 5.2\,fb$^{-1}$ of data collected with the CMS detector. The forward-backward asymmetry of the muons $A_{FB}$, the ${\rm...

description The angular distributions and the differential branching fraction of the decay ${\rm B}^{0} \rightarrow {\rm K}^{*0} \mu^{+} \mu^{-}$ are studied using an integrated luminosity of 5.2\,fb$^{-1}$ of data collected with the CMS detector. The forward-backward asymmetry of the muons $A_{FB}$, the ${\rm K}^{\ast 0}$ longitudinal polarization fraction $F_{L}$, and the differential branching fraction ${\rm d}\mathcal{B}/{\rm d}q^{2}$, are determined as a function of the dimuon invariant mass squared. The measurements are in good agreement with the standard model.
