Study of W boson production in pPb collisions at √sNN = 5.02 TeV. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 750, 565-586. doi:10.1016/j.physletb.2015.09.057 | Abstract: | The first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb−1 at a nucleon–nucleon centre-of-mass energy of sNN=5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward–backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c, and as a function of the lepton pseudorapidity in the |ηlab|<2.4 range. Deviations from the expectations based on currently available parton distribution functions are observed, showing the need for including W boson data in nuclear parton distribution global fits. © 2015 CERN for the benefit of the CMS Collaboration | URI: | https://doi.org/10.1016/j.physletb.2015.09.057 | ISSN: | 0370-2693 |
