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

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

The forward-backward charge asymmetry for the process (Formula presented). 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...
