Query: Search for $Z'$ via $ZH$ associated production at LHC   Many new physics models predict the existence of extra neutral gauge bosons
($Z'$). Inspired by the recent development on Higgs search, we study the
properties of $Z'$ via the Higgs and $Z$ boson associated production. The
couplings of $Z'$ to quarks can be investigated through $pp \to Z'\to ZH\to
l^+l^-b \bar b$ process, which also provides extraordinary signal for
understanding the properties of $Z'ZH$ 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 $Z'$ to quarks via $Z'ZH$ interaction.
