Four-jet Signal at LEP2 and Supersymmetry

ALEPH has reported a significant excess of four-jet events in the LEP runs above the $Z^0$ resonance, which however has not been confirmed by the other LEP collaborations. We assume here that this excess corresponds to a physics signal and try to interpret it in the context of supersymmetric models...

description ALEPH has reported a significant excess of four-jet events in the LEP runs above the $Z^0$ resonance, which however has not been confirmed by the other LEP collaborations. We assume here that this excess corresponds to a physics signal and try to interpret it in the context of supersymmetric models with $R$-parity violation. Associated production of a left and right selectron can explain all the distinctive features of the ALEPH data: the value of the cross section, the di-jet mass difference, the absence of bottom quarks in the final state, and the di-jet charge content. Our proposed scenario makes definite predictions which can be tested at future LEP runs at higher energies.
