Measurement of the Inclusive W and Z Cross Sections in pp Collisions with the CMS Detector

We describe methods developed with simulated events for an early measurement of the inclusive W and Z cross sections with the CMS detector, assuming 10~pb$^{-1}$ of proton proton collisions. A simple and robust selection is used. The selection is intended to be tolerant of the anticipated imperfecti...

description We describe methods developed with simulated events for an early measurement of the inclusive W and Z cross sections with the CMS detector, assuming 10~pb$^{-1}$ of proton proton collisions. A simple and robust selection is used. The selection is intended to be tolerant of the anticipated imperfections in calibration and alignment of the CMS detector in the early data-taking period. Data-driven methods have been devised to measure selection efficiencies, to tune the selection cuts, and to estimate the backgrounds for the W channel. The main sources of systematic uncertainty in the W and Z yield measurement are described.
