  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 $\mu^+\mu^-\toH_i^0Z^0$, $\mu^+\mu^-\to
H^{\pm}W^{\mp}$.
