Determination of alpha_s and W boson leptonic branching ratio from the W and Z cross sections

We try to determine the strong coupling alpha_s and the W boson leptonic branching ratio from the W and Z boson production cross section through pp collisions in the LHC. We run the MCFM program together with LHAPDF or HERAPDF les to extract the theoretical prediction of cross sections at different...

description We try to determine the strong coupling alpha_s and the W boson leptonic branching ratio from the W and Z boson production cross section through pp collisions in the LHC. We run the MCFM program together with LHAPDF or HERAPDF les to extract the theoretical prediction of cross sections at different alpha_s in different experiments. We compare the predicted values and the experimental results to do a precise measurement of alpha_s and the branching ratio.
