Search for SM Higgs in WH to WWW to 3l 3nu

This document reports on a search for the associated WH Higgs boson production in the three lepton final state in pp collisions at $\sqrt{s} = $ 7 and 8~$\mathrm{Te\kern -0.1em V}$. The analysis is performed using the LHC data recorded with the CMS detector, corresponding to an integrated luminosity of about 10~fb$^{-1}$. Candidates are selected in events with three leptons, electrons or muons, large transverse missing energy and low hadronic activity. No significant excess of events above the standard model background expectation is observed. The observed (expected) upper limits on the WH cross section at the 95\% confidence level are about 4.8 (5.0) times larger than the standard model predicted cross section for $m_{\mathrm{H}}=125~\,\mathrm{Ge\kern -0.1em V}$.
