Parity Violating Signals for Chargino Production at LEP II
نویسنده
چکیده
We study chargino pair production at LEP II in supersymmetric models with spontaneously broken R–parity. We perform a detailed 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. We determine the limits on the chargino mass as a function of the magnitude of the effective R– parity violation parameter ǫ. As ǫ → 0 we recover the usual MSSM chargino mass limits, however, for ǫ sufficiently large, the bounds on the chargino mass can be about 15 GeV weaker than in the MSSM due to the dominance of the two-body chargino decay mode χ+ → τ+J , where J denotes the Majoron. Moreover, we show that LEP II can detect signals of spontaneous R–parity violation in a large region of the parameter space if charginos are observed.

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 کاملSingle chargino production with R - parity lepton number violation in electron - electron and muon -
We examine single chargino production in conjunction with R-parity lepton number violation in future lepton-lepton collisions. Present bounds on R-parity violating couplings allow for a production cross section of the order of O(10 fb) for a wide range of sneutrino and chargino masses. Scenarios of chargino decay which lead to purely leptonic signals in the final state and without missing energ...

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...
متن کاملR-parity-breaking SUSY solution to the Rb and ALEPH anomalies.
We discuss an optimal R-parity breaking SUSY solution to the Rb excess as well as the ALEPH 4-jet anomaly. The latter arises from the pair production of stop via chargino decay at LEP1.5, followed by its R–violating decay into a light quark pair. The model satisfies top quark and Z–boson decay constraints along with gaugino mass unification. CERN-TH/96-203 August, 1996 [email protected] dpro...
