Search for $Z^{\prime }$ via $ZH$ associated production at LHC

Abstract

Many new physics models predict the existence of extra neutral gauge bosons ($Z^{\prime }$). Inspired by the recent development on Higgs search, we study the properties of $Z^{\prime }$ via the Higgs and $Z$ boson associated production. The couplings of $Z^{\prime }$ to quarks can be investigated through $pp\to Z^{\prime }\to ZH\to l^{+}{l}^{-}b\bar{b}$ process, which also provides extraordinary signal for understanding the properties of $Z^{\prime }ZH$ interaction. The standard model background processes can be significantly suppressed by adopting appropriate kinematic cuts. The charged lepton angular distributions are related to the ratio of chiral couplings of $Z^{\prime }$ to quarks via $Z^{\prime }ZH$ interaction.
