Differentiating the production mechanisms of the Higgs-like resonance using inclusive observables at hadron colliders
arXiv:1308.5453 · doi:10.1007/JHEP02(2014)094
Abstract
We present a study on differentiating direct production mechanisms of the newly discovered Higgs-like boson at the LHC based on several inclusive observables. The ratios introduced reveal the parton constituents or initial state radiations involved in the production mechanisms, and are directly sensitive to fractions of contributions from different channels. We select three benchmark models, including the SM Higgs boson, to illustrate how the theoretical predictions of the above ratios are different for the , , and (flavor universal) initial states in the direct production. We study implications of current Tevatron and LHC measurements. We also show expectations from further LHC measurements with high luminosities.
