R – Parity Violating Signals for Chargino Production at LEP II
We study chargino pair production at LEP II in supersymmetric models with spontaneously broken R–parity. We perform signal and background analyses, showing that a large region of the parameter space of these models can be probed through chargino searches at LEP II. In particular, we determine the attainable limits on the chargino mass as a function of the magnitude of the effective bilinear R–p...
متن کاملDistinctive Signals of Spontaneous R-parity Breaking at Lep-ii
We consider the signals of pair-produced charginos in an ee collider, in a scenario where R-parity is spontaneously broken. The possibility of lepton-chargino mixing, together with the presence of a Majoron, opens up the two-body decay channel of a chargino into a tau and a Majoron. We have studied the regions where this is the dominant decay of a chargino, and have shown that over a large regi...

We illustrate the sensitivities of LEP experiments to leptonic signals associated to models where supersymmetry (SUSY) is realized with spontaneous breaking of R-parity. We focus on missing transverse momentum plus acoplanar muon events (p /T + μ μ) arising from lightest neutralino single production χν as well as pair production χχ, followed by χ decays, where χ denotes the lightest neutralino....
متن کاملR-Parity Violating Signals at Existing Colliders
Formation of the s-channel slepton resonances at LEP2 or Tevatron at current energies is an exciting possibility in R-parity violating SUSY models. Existing LEP2 and Tevatron data can be exploited to look for sleptons, or to derive bounds on the Yukawa couplings of sleptons to quark and lepton pairs. Invited talk at the 12th Les Rencontres de Physique de la Vallée d’Aoste, La Thuile, Aosta Vall...
