摘要：

We discuss the recently observed excess of high lepton momentum transfer, Q(2), neutral current deep inelastic scattering events at HERA in the light of supersymmetry with broken R-parity. We find more than one possible solution. We consider the possibilities for testing these hypotheses at HERA, the Tevatron and at LEP. One lepton-number violating operator can account for both the HERA data and the four-jet anomaly seen by ALEPH at LEP. (C) 1997 Elsevier Science B.V. PACS: 11.30.Pb; 12.60.Jv; 14.80.Ly.
