$R$-Parity Violation and Scalar Leptons Production at Lepton- Antilepton Colliders

In the framework of models with R-parity violation, scalar neutrinos and scalar leptons production in the processes $l_i^+l_j^-\to\tilde {\nu}_{k,L} Z^0$and$l^+_il^-j\to \tilde{l}^{\mp}{k,L}W^{\pm}$ is considered.We also consider within the Minimal Supersymmetric Standard Model Higgs bosons production in the processes ${\mu }^{+}{\mu }^{-}{\text{toH}}_i^0{Z}^0$, $\mu^+\mu^-\to H^{\pm}W^{\mp}$.
