Chargino production at an e−e− collider

Abstract

The chargino pair production in $e^-e^-$ collisions with their subsequent decays are considered within SUSY models with R-parity violation and with lepton number non-conservation. The production process ($\sqrt{s}=1$ TeV) is predicted to be large in a wide range of both sneutrino and chargino masses. The influence of all virtual sneutrino states and their mixings with electrons are taken into account. Some specific situations are pointed out when significant suppressions of the cross section can take place. The chargino decays are discussed for either the chargino as LSP or the chargino as heavier sparticle. In both cases unique signals are possible with up to six charged fermions and without missing energy.
