Higgs production in association with bottom quark pair at LHC

Abstract

The direct observation of the Yukawa interaction related to Standard Model Higgs and the bottom quark is obtained from the $h\to b\bar{b}$ process recently. The b-tagging becomes an important tool to search for new heavy resonance production at LHC. We use the b-tagging method to investigate the neutral Higgs production in association with a bottom quark pair, and perform the detector simulation for the signal process with the Higgs decaying into $b\bar{b}$ or ${\tau }^{+}{\tau }^{-}$ together with the dominant backgrounds. Our results show that $b\bar{b}b\bar{b}$ and $b\bar{b}{\tau }^{+}{\tau }^{-}$ processes will play an important role to search for the exotic heavy Higgs production at LHC and future hadron colliders.
