Searches for the technicolor signatures via gg --> W^{\pm}π_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}π_t^{\mp}, is several dozen femtobarns with reasonable values of the parameters, and the total cross section of pp --> W^{\pm}π_t^{\mp} can reach a few hundred femtobarns when we consider the sum of the contributions of these two parton subprocesses gg --> W^{\pm}π_t^{\mp} and b\bar{b} --> W^{\pm}π_t^{\mp}.

Technicolor corrections to b\bar{b} -> W^{\pm}π^{\mp}_t at the CERN Large Hadron Collider

In this paper we calculate the technicolor correction to the production of a charged top pion in association with a W boson via b\bar{b} annihilation at the CERN Large Hadron Collider in the context of the topcolor assisted technicolor model. We find that the cross section of pp \rightarrow b\bar{b} -> W^{\pm}π_t^{\mp} at the tree level can reach a few hundred femtobarns for reasonable ranges of the parameters, roughly corresponding to the result of the process pp -> b\bar{b} -> W^{\pm}H^{\mp} in the minimal supersymmetric standard model; the relative corrections arising from the one-loop diagrams are about a few percent to two dozen percent, and they will increase the cross section at the tree level. As a comparison, we also discuss the size of the hadron cross section via the other subprocess gg -> W^{\pm}π_t^{\mp}.
