Abstract
In this paper I discuss the search for a Standard Model (SM) Higgs boson in the diphoton plus missing transverse energy (missing ET or EMISS T ) channel using 20.7 fb−1 of data recorded by the ATLAS detector in the year 2012. Higgs boson at LHC can be generated through different processes: gluon-gluon fusion (∼ 85%), vector boson fusion (∼ 10%), W/Z associated production (∼ 5%) and top-antitop fusion (< 1%). The applied selection is optimized to isolate events from Higgs boson production associated with a W or Z boson requiring the presence of EMISS T from Z/W decay into neutrinos in addition to two isolated energetic photons. The sensitivity of this analysis is presented and found to be at a level above 5 times the predicted Standard Model cross-section.
