Supersymmetric Left-Right Model and its Tests in Linear Colliders

We investigate phenomenological implications of a supersymmetric left-right model based on $SU(2{)}_L\times SU(2{)}_R\times U(1{)}_{B-L}$ gauge symmetry testable in the next generation linear colliders. We concentrate in particular on the doubly charged $SU(2{)}_R$ triplet higgsino $\tilde{\mathrm{\Delta }}$, which we find very suitable for experimental search. We estimate its production rate in $e^{+}{e}^{-}$, $e^{-}{e}^{-}$, $e^{-}\gamma$ and $\gamma \gamma$ collisions and consider its subsequent decays. These processes have a clear discovery signature with a very low background from other processes.
