$γ γ \to t c ˉ + c t ˉ$ in a supersymmetric theory with an explicit R-parity violation

Abstract

We studied the process $γ γ \to t c ˉ + c t ˉ$ in a $R_{p}$ violating supersymmetric Model with the effects from both B- and L-violating interactions. The calculation shows that it is possible to detect a $R_{p}$ violating signal at the Next Linear Collider. Information about the B-violating interaction in this model could be obtained under very clean background, if we take the present upper bounds for the parameters in the supersymmetric $/ R_{p}$ interactions. Even if we can not detect a signal of $/ R_{p}$ in the experiment, we may get more stringent constraints on the heavy-flavor $/ R_{p}$ couplings.
