SM H→WW→ℓνℓν analysis with the ATLAS detector at the LHC — •pai-hsien jennifer hsu, olivier arnaez, volker büscher, frank fiedler, johannes mattmann, sebastian moritz, christian schmitt, and natalie wieseotte — Johannes-Gutenberg-Universität Mainz

In summer 2012, both the ATLAS and the CMS collaborations at the Large Hadron Collider (LHC) have announced the discovery of a new neutral boson. The mass of the new boson is around 125 GeV, and the excess is consistent with the Standard Model (SM) prediction of a Higgs Boson. One of the leading discovery channels is the search of a Higgs boson decaying into two W bosons in the leptonic final states, H→WW→ℓνℓν. However the signal in this channel has only been observed in the gluon-gluon fusion production, and therefore the current emphasis is on the measurement in the vector boson fusion production. I will give an overview of the H→WW→ℓνℓν analysis, and report on the latest results from the ATLAS collaboration.
