Boosting Higgs boson discovery: The forgotten channel

Abstract

Searches for a heavy standard model Higgs boson focus on the ``gold plated mode'' where the Higgs decays to two leptonic $Z$ bosons. This channel provides a clean signature, in spite of the small leptonic branching ratios. We show that using fat jets the semileptonic $ZZ$ mode significantly increases the number of signal events with a similar statistical significance as the leptonic mode.
