Charged top-pion production associated with the bottom quark pair as a probe of the topcolor-assisted technicolor model at the LHC.

The topcolor-assisted technicolor (TC2) model predicts the existence of the charged top-pions (πt±), whose large couplings with the third generation fermions will induce the charged top-pion production associated with the bottom and antibottom quark pair at the CERN Large Hadron Collider (LHC) through the parton processes cb¯ → πt+bb¯ and ud¯(cs¯) → πt+bb¯. In this report, we examine these productions and find that, due to the small standard model backgrounds, their production rates can exceed the 3σ sensitivity of the LHC in a large part of parameter space, so these processes may serve as a good probe of the TC2 model.
