Associate Production of the top-Pion with b Quark Pair in TC2 Model at High Energy e+e Colliders

  • In this paper we investigate the production of top-pion π0 t of the topcolor assisted technicolor (TC2) model with b quark pair at e+e- colliders. We find that the cross section of the process e+e→b bπ0 t is larger than that of e+e→b bH0 in the standard model,and is approximately the same as that of the process e+e→b bh0(b bH0,b bA0)in the minimal supersymmetric model. With reasonable values of the parameter,the cross section can reach 10fb. The neutral top-pion π0 t may be observed directly via this process at the next linear colliders.

Abstract: In this paper we investigate the production of top-pion π0 t of the topcolor assisted technicolor (TC2) model with b quark pair at e+e- colliders. We find that the cross section of the process e+e→b bπ0 t is larger than that of e+e→b bH0 in the standard model,and is approximately the same as that of the process e+e→b bh0(b bH0,b bA0)in the minimal supersymmetric model. With reasonable values of the parameter,the cross section can reach 10fb. The neutral top-pion π0 t may be observed directly via this process at the next linear colliders.
