Measurement of Inclusive $W$ Production Cross Section in the Electron Channel

Precision electroweak measurements are one of the first priorities for the LHC physics program with the first data. We discuss measurement of the W production cross section in the electron decay channel usng the dta-driven approach to estimate signal efficiency and the background. The expected measurement uncertainties for the data sets corresponding to the integrated luminosities between 100 pb$^{-1}$ and 1 fb$^{-1}$ are discussed.
