Measurement of the forward-backward asymmetry in Z/γ∗ -> μ+μ− decays and determination of the effective weak mixing angle

Abstract:

The forward-backward charge asymmetry for the process qq̅Zμ+μ is measured as a function of the invariant mass of the dimuon system. Measurements are performed using proton proton collision data collected with the LHCb detector at √s=7 and 8 TeV, corresponding to integrated luminosities of 1 fb−1 and 2 fb−1 respectively. Within the Standard Model the results constrain the effective electroweak mixi...
