Inclusive W boson QCD predictions and lepton charge asymmetry in proton-proton collisions at root s=14 TeV

摘要

Inclusive W (W - l(+/-)nu) boson QCD predictions and lepton charge asymmetry in proton-proton collisions at root s = 14 TeV is performed in this study. Total and fiducial cross section predictions are obtained up to next to next to leading order (NNLO) QCD corrections using Monte Carlo for FeMtobarn processes (MCFM) MC generator. To validate the predictions, a detailed comparison of NNLO QCD calculations with 8 TeV CMS results is performed. To discuss the advantage of the higher order QCD predictions on the scale uncertainty, a scale dependence study is presented based on the choice of renormalization (mu(R)) and factorization (mu(F)) scale variations. W boson - lepton charge asymmetry and differential cross section as a function of lepton pseudorapidity at root s = 14 TeV are further performed in 11 vertical bar eta vertical bar regions.
