At an e^+ e^- collider, charged top-pion can be produced via the processes e^+e^- → t^bπt^-(^tbπt^+). At a γγ collider, it can be produced via the processes γγ →t^bπt^-(t^-bπt^+). The cross section can reach to a few of fb depending on the mass of the charged top-pion.展开更多

文摘We study the charged top-pion in the topcolor assisted technicolor model(TC2), and calculate the production of charged top-pion at e^+ e^- and γγ colliders. At an e^+ e^- collider, charged top-pion can be produced via the processes e^+e^- → t^bπt^-(^tbπt^+). At a γγ collider, it can be produced via the processes γγ →t^bπt^-(t^-bπt^+). The cross section can reach to a few of fb depending on the mass of the charged top-pion.
