Abstract

Measurements of the production of the W± and Z0 bosons at midrapidity in pp collisions at √s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are pre- sented. The W± and Z0 bosons are detected via their (di)electronic decay channels, with the electron reconstruc- tion performed in the midrapidity region (|y| < 0.6). The pT-integrated and pT-differential production cross sections of electrons from W± decays in the interval 30 < pT < 60 GeV/c, as well as the pT-integrated production cross sec- tion of Z0 bosons, are measured. The results are described by perturbative QCD calculations using different sets of par- ton distribution functions. The production of W± bosons and azimuthally correlated associated hadrons is also measured as a function of the charged-particle multiplicity for the first time at the LHC. The former increases approximately linearly with the charged-particle multiplicity, while for the latter, there are hints of a faster-than-linear increase. These obser- vations are compared with theoretical calculations
