Measurement of the forward-backward asymmetry in $Z/{\gamma }^{\ast }\to {\mu }^{+}{\mu }^{-}$ decays and determination of the effective weak mixing angle

LHCb collaboration, R. Aaij, B. Adeva +722

The forward-backward charge asymmetry for the process $q\bar{q}\to Z/{\gamma }^{\ast }\to {\mu }^{+}{\mu }^{-}$ is measured as a function of the invariant mass of the dimuon system.…
