摘要
In this paper we calculate the production of a charged top pion in association with a W boson at the CERN Large Hadron Collider (LHC) in the context of the topcolor assisted technicolor model. We find that the cross section of pp → bb^- → W^±πt^干 is roughly corresponding to the result of the process pp → bb^- → W^±πt^干= in the minimal supersymmetric standard model, and for reasonable ranges of the parameters, the cross section can reach a few hundred fb. The W^±πt^干 signal should be clearly visible at LHC unless π t^± is very heavy.
