Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Measurements of the production of the $W^{\pm}$ and $Z^0$ bosons at midrapidity in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The $W^{\pm}$ and $Z^0$ bosons are detected via their (di)electronic decay channels, with the electron reconstruction performed in the midrapidity region ($|y| < 0.6$). The $p_T$-integrated and $p_T$-differential production cross sections of electrons from $W^{\pm}$ decays in the interval $30 < p_T < 60$ GeV/c, as well as the $p_T$-integrated production cross section of $Z^0$ bosons, are measured. The results are described by perturbative QCD calculations using different sets of parton distribution functions. The production of $W^{\pm}$ 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 observations are compared with theoretical calculations .
