Sensitivity to anomalous WZ production models with early data

Abstract

In this article we describe the methods of observing WZ signal at CMS experiment at Large Hadron Collider. To reduce the dependence on Monte Carlo simulation we use data-driven techniques and estimate that 5sigma significance of WZ signal can be reached with less than 350 pb^{-1} at 95% C.L. for sqrt{s} = 14 TeV. We also overview several models that would yield anomalous production of the WZ final state, sensitivity to which can be achieved with less data.
