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 qq→Z/γ∗→μ+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 ...
Measurement of forward Z → e+e− production s√s=8 TeV
A measurement of the cross-section for Z-boson production in the forward region of pp collisions at 8 TeV centre-of-mass energy is presented. The measurement is based on a sample of Z → e+e− decays reconstructed using the ...
Measurement of the exclusive Υ production cross-section in pp collisions at √s=7 TeV and 8 TeV
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in ...
Measurement of the forward Z boson production cross-section in pp collisions at √s =7 TeV
A measurement of the production cross-section for Z bosons that decay to muons is presented. The data were recorded by the LHCb detector during pp collisions at a centre-of-mass energy of 7 TeV, and correspond to an ...
