英文摘要: In the Minimal Supersymmetric Model (MSSM) the hitherto unconstrained flavor mixing between top-squark and charm-squark will induce the flavor-changing neutral-current (FCNC) interaction between top quark and charm quark, which then lead to various processes at the next generation linear collider (NLC), i.e., the top-charm associated productions via a(+)e(-), e(-) gamma and gammagamma collisions as well as the top quark rare decays t --> cV (V = g, gamma or Z). All these processes involve the same part of the parameter space of the MSSM. Through a comparative analysis for all these processes at the NLC, we found that the best channel to probe such SUSY-induced top quark FCNC is the top-charm associated production in gammagamma collision, which occurs at a much higher rate than a(+)e(-) or e(-) gamma collision and may reach the detectable level for some part of the parameter space.
