Production of the neutral top-pion at the eγ colliders

In the framework of the top-color-assisted technicolor (TC2) model, we study a neutral top-pion production process e-γ→e-Πt0 in this paper. Our results show that the production cross section of e-γ→e-Πt0 can reach the level of several tens of femtobarns, and over 103 neutral top-pion events can be produced in the planned e+e- linear colliders each year. Therefore, such a top-pion production process provides us a unique chance to detect top-pion events and test the TC2 model. On the other hand, the cross section of e-γ→e-Πt0 is about one order of magnitude larger than those of some similar processes in the standard model (SM) and the minimally supersymmetric standard model (MSSM) [i.e., e-γ→e-H in the SM and e-γ→e-H0(A0,h0) in the MSSM]. So we can easily distinguish the neutral top-pion from other neutral Higgs bosons in the SM and MSSM
