Abstract

CERN-LHC. The angular distributions and the differential branching fraction of the decay ${\rm B}^0 \to {\rm K^*(892)}^0 μ^+ μ^-$ are studied using data corresponding to an integrated luminosity of 20.5 fb$^{-1}$ collected with the CMS detector at the LHC in pp collisions at $\sqrt{s} = 8$ TeV. From 1430 signal decays, the forward-backward asymmetry of the muons, the ${\rm K^*(892)}^0$ longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. ; Other ; The measured values of signal yield, FL, AFB, and differential branching fraction in bins of the dimuon invariant mass squared. The (FL,AFB) correlation factors are also shown.
