Abstract
We study the process $\gamma\gamma \rightarrow t \bar{c} + c \bar{t}$ in a R_p-violating supersymmetric model with the effects of both B- and L-violating interactions. The calculation shows that it is possible to detect a R_p-violating signal at the Linear Collider. Information about the B-violating interaction in this model could be obtained with a very clean background, if we take the present upper bounds for the parameters in the supersymmetric $\rlap/ R_{\mathrm {p}}$ interactions. Even if we cannot detect a signal of $\rlap/ R_{\mathrm {p}}$ in the experiment, we may get more stringent constraints on the heavy-flavor $\rlap/ R_{\mathrm {p}}$ couplings.
