      abstract     = {We study the single chargino production $e^+ e^- \to \tilde
                      \chi^{\pm} \mu^{\mp}$ at linear colliders which occurs
                      through the $\lambda_{121}$ R-parity violating coupling
                      constant. We focus on the final state containing 4 leptons
                      and some missing energy. The largest background is \susyq
                      and can be reduced using the initial beam polarization and
                      some cuts based on the specific kinematics of the single
                      chargino production. Assuming the highest allowed
                      supersymmetric background, a center of mass energy of $\sqrt
                      s=500$ GeV and a luminosity of ${\cal L}=500$ fb$^{-1}$, the
                      sensitivities on the $\lambda_{121}$ coupling constant
                      obtained from the single chargino production study improve
                      the low-energy experimental limit over a range of $\Delta
                      m_{\tilde \nu} \approx 500$ GeV around the sneutrino
                      resonance, and reach values of $\sim 10^{-4}$ at the $\tilde
                      \nu$ pole. The single chargino production also allows to
                      reconstruct the $\tilde \chi_1^{\pm}$, $\tilde \chi_2^{\pm}$
                      and $\tilde \nu$ masses. The initial state radiation plays a
                      fundamental role in this study.},
