Measurement of the Drell-Yan forward-backward asymmetry and of the effective leptonic weak mixing angle in proton-proton collisions at Vs=13TeV
The forward-backward asymmetry in Drell-Yan production and the effective leptonic electroweak mixing angle are measured in proton-proton collisions at Vs=13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 138 fb-1. The measurement uses both dimuon and dielectron...

CMS Electroweak Mixing angle Drell-Yan |
| description |
The forward-backward asymmetry in Drell-Yan production and the effective leptonic electroweak mixing angle are measured in proton-proton collisions at Vs=13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 138 fb-1. The measurement uses both dimuon and dielectron events, and is performed as a function of the dilepton mass and rapidity. The unfolded angular coefficient A4 is also extracted, as a function of the dilepton mass and rapidity. Using the CT18Z set of parton distribution functions, we obtain sin2 0eff=0.23152 +- 0.00031, where the uncertainty includes the experimental and theoretical contributions. The measured value agrees with the standard model fit result to global experimental data. This is the most precise sin2 0eff measurement at a hadron collider, with a precision comparable to the results obtained at LEP and SLD. |
