Searches for the technicolor signatures via gg --> W^{\pm}\pi_t^{\mp} at   the Large Hadron Collider
  In this paper we calculate the production of a charged top pion in association with a W boson via gg fusion at the CERN Large Hadron Collider in the context of the topcolor assisted technicolor model. We find that, the total cross section of pp --> gg --> W^{\pm}\pi_t^{\mp}, is several dozen femtobarns with reasonable values of the parameters, and the total cross section of pp --> W^{\pm}\pi_t^{\mp} can reach a few hundred femtobarns when we consider the sum of the contributions of these two parton subprocesses gg --> W^{\pm}\pi_t^{\mp} and b\bar{b} --> W^{\pm}\pi_t^{\mp}.
