W and Z physics with CMS

I will present measurements of inclusive W and Z vector boson production 

rates for pp collisions at 7 TeV c.m. energy, based on the decays of the W 

and Z bosons into electrons and muons in the CMS detector at the Large 

Hadron Collider. I will then show a comparison of these measurements 

and the ratio of W and Z production rates with theoretical predictions computed 

at the level of next-to-next-to-leading-order (NNLO) in perturbative QCD. 

Finally, I will give an overview of the precision electroweak measurements 

at LHC and their usefulness in constraining the parton distribution function 

and to search for physics beyond the Standard Model.
