    • نبذة مختصرة :
      The first study of the angular distribution of μ+ μ− pairs produced in the forward rapidity region via the Drell-Yan reaction pp → γ*/Z + X → l+ l− + X is presented, using data collected with the LHCb detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.1 fb^−1. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. The results are compared to various theoretical predictions of the Z-boson production mechanism and can also be used to probe transverse-momentum-dependent parton distributions within the proton.
