Precision electroweak measurements in CMS

The CMS collaboration at the CERN Large Hadron Collider has collected an unprecedented data sample from proton-proton collisions at a center-of-mass energy of 13TeV. The data sample, consisting of a total integrated luminosity of 140/fb, allows for even more precise measurements of standard model electroweak parameters, and gives access to rare electroweak final states, which provide new handles to test the consistency of the standard model.
