Prospects for first measurement of the WW production cross-section in pp collisions at 10 TeV center of mass energy with the CMS detector

This note describes an analysis strategy for measuring the $WW$ production cross-section in 100~pb$^{-1}$ of $pp$ collision data at $\sqrt s = $ 10~TeV. Based on Monte Carlo simulations of $WW$ and the major background processes, we explore suitable background reduction cuts and develop data-driven methods to estimate those backgrounds. We present the event yields and statistical and systematic uncertainties that we expect to achieve with this analysis strategy. We estimate a total uncertainty on the cross-section of 30\% or better.
