W±π Associated Production in TOPCMTC Model at LHC

  • In this paper we calculate the production of a charged technipion in association with a W boson at the CERN Large Hadron Collider(LHC)in the context of the topcolor assisted multiscale technicolor(TOPCMTC)model.We find that the cross section of pp→b→W±π is roughly corresponding to the result of the process pp→b→W±H in the minimal supersymmetric standard model,and for reasonable ranges of the parameters,the cross section can reach some dozens or even more than one hundred fb.The W±π signal may be clearly visible at LHC.
