Many new physics models predict the existence of TeV-scale charged gauge boson W^\ensuremath' together with Higgs-boson(s). We study the W^\ensuremath'WH interaction and explore the angular distribution of charged leptons to distinguish WR^\ensuremath'WH from WL^\ensuremath'WH in the pp\ensuremath→HW\ensuremath→bbl\ensuremathν process at the LHC. It is found that a new type forward-backward asymmetry (AFB) relating to the angle between the direction of the charged lepton in the W rest frame and that of the reconstructed W^\ensuremath' in the laboratory frame is useful to investigate the properties of W^\ensuremath'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 AFB can reach 0.03(\ensuremath-0.07) for WR^\ensuremath'(WL^\ensuremath') production at √(S)=14 TeV.
