摘要：
Many new physics models predict the existence of TeV-scale charged gauge boson W ' together with Higgs-boson(s). We study the W ' WH interaction and explore the angular distribution of charged leptons to distinguish W '(R) WH from W '(L) WH in the pp -> HW -> b (b) over bar l nu process at the LHC. It is found that a new type forward-backward asymmetry (A(FB)) relating to the angle between the direction of the charged lepton in the W rest frame and that of the reconstructed W ' in the laboratory frame is useful to investigate the properties of W ' WH interaction. We analyze the standard model backgrounds and develop a set of cuts to highlight the signal and suppress the backgrounds at LHC. We find that A(FB) can reach 0.03(-0.07) for W '(R)(W '(L)) production at root S = 14 TeV.
