dc.description.abstractThis paper presents a phenomenological study for the differential cross section of the forward Z boson production in leptonic decay channels as a function of the angular variable phi(eta)* in proton-proton collisions. The phi(eta)* distribution is predicted for the forward pseudorapidity region 2.0 <.. l < 4.5 of the decay leptons at center-of-mass energies of 8, 13, and 14 TeV. Accurate prediction of the phi(eta)* distribution is achieved by means of state-of-the-art calculations including fixed-order perturbative QCD and large logarithmic corrections. The predicted distributions are obtained by employing the resummation either at next-to-next-to-leading logarithmic (NNLL) or next-to- NNLL (N 3LL) accuracy which is matched to the perturbative QCD calculation at next- to-next-to-leading order ( NNLO) accuracy, that is at NNLO+NNLL and NNLO+N 3LL, respectively. The Z boson phi(eta)* variable is experimentally preferable as it has been measured more precisely than the Z boson transverse momentum, though both variables probe the same physics; therefore, an accurate description of the phi(eta)* variable is required using theoretical predictions at both NNLO+NNLL and NNLO+N-3 LL accuracies. The matched predictions are compared with the available 8-TeV and 13-TeV measurements by the LHCb experiment at the LHC and found to be in good agreement. The 14-TeV predicted distributions at both NNLO+NNLL and NNLO+N-3 LL are also reported. In all the predicted results, the NNLO+N-3 LL provides more improved accuracy for the reliable description of the phi(eta)* distribution throughout its entire phase space region.en_US
