Chargino Pair Production at LEP2 with Broken R-Parity: 4-jet Final States
نویسندگان
چکیده
We study the pair production of charginos in e+e−-collisions followed by the decay via R-parity violating LQD̄ operators. We determine the complete matrix element squared for chargino decays via LQD̄ or LLĒ operators. We find regions in MSSM parameter space where the chargino mass is 52.5GeV and the R-parity violating decays of the charginos dominate the gauge decays to neutralinos. At LEP2 this then leads to additional 4 jet events which could explain the excess recently observed by ALEPH. Submitted to Physics Letters B.

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 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...

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 (√ 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...
متن کاملALEPH Four - Jet Excess , R b and R − Parity Violation ∗
We review briefly the indications for some relatively light superpartners based on the Rb anomaly and discuss the dependence of the potential increase in Rb on the assumption about R−parity (non)conservation. We point out that the exotic 4-jet events reported by ALEPH may constitute a signal for supersymmetry with such a light spectrum and with explicitly broken R−parity. A parton level simulat...
