Latest results on inclusive W/Z production at CMS

At the LHC, inclusive production of W and Z bosons offer a unique window to perform stringent tests of theoretical predictions based on the Standard Model (SM) and probe its fundamental parameters. With the large samples of W and Z events collected with the CMS detector, many processes have been studied at an unprecedented precision. These measurements test the SM predictions up to next-to-next-to-leading order and provide valuable inputs to improve the theoretical framework used to model LHC physics. In the following we will concentrate on the measurement of the fiducial Drell-Yan ($DY$) to muons cross-section at the $Z$-boson mass peak, double differentially in transverse momentum ($P_T(Z)$) and rapidity ($Y(Z)$), as it was presented for the first time during this conference.
