Search for a heavy Higgs boson in $H\to ZZ\to 2\ell 2\hat{I}½$ channel in pp collisions with CMS detector at the LHC

Abstract

A search for a heavy Higgs boson in the $H\to ZZ\to 2\ell 2\hat{I}½$ decay channel, where $\ell$ = e or $\hat{I}¼$, in pp collisions at a centre-of-mass energy of 7 and 8 TeV is presented. The search is optimized separately for the vector boson fusion and the gluon fusion production processes. No significant excess is observed above the background expectation. A re-interpretation of the results as a search for an electroweak singlet extension of the Standard Model is also presented.
