The CDF collaboration has analyzed almost 6 f b−1 of data collected at the Tevatron Collider at sqrt(s) = 1.96 TeV to search for Standard Model Higgs boson through the decay into W+W−. Starting from events with two leptons, advanced analysis techniques are applied to better discriminate signal from background. The Higgs sensitivity is maximized combining together analysis that exploit different event topologies. No significant excess over the expected background is observed and data is used to set a limit in units of Standard Model expectations. The limit plays a fundamental role in the Higgs search excluding the existence of this particle with mass between 158 and 175 GeV/c2 when combined with D0, the other Tevatron experiment.

Abstract
The CDF collaboration has analyzed almost 6 f b−1 of data collected at the Tevatron Collider at sqrt(s) = 1.96 TeV to search for Standard Model Higgs boson through the decay into W+W−. Starting from events with two leptons, advanced analysis techniques are applied to better discriminate signal from background. The Higgs sensitivity is maximized combining together analysis that exploit different event topologies. No significant excess over the expected background is observed and data is used to set a limit in units of Standard Model expectations. The limit plays a fundamental role in the Higgs search excluding the existence of this particle with mass between 158 and 175 GeV/c2 when combined with D0, the other Tevatron experiment.Pubblicazioni consigliate
