Abstract
The evidence for the SM Higgs-like boson in the H → WW(∗) → lνlν channel using the complete data samples collected in 2011 and 2012 by the ATLAS experiment at the LHC, at a centre of mass energy of 7TeV and 8TeV, respectively, is presented. The total integrated luminosity is about 25 fb−1. The analysis focuses on a SM Higgs boson with a mass of 125.5 GeV produced through gluon-gluon fusion (ggF) and vector-boson fusion (VBF). An excess over the expected number of background events is observed with a significance of 3.8 standard deviations, and the expected value is 3.8. The signal strenght is consistent with the Standard Model expectation. The combined result with WH → WWW(∗) → lνlνlν and ZH → ZWW(∗) → lllνlν is also reported.
