R-parity violation in superstring derived models

Abstract

The ALEPH collaboration has recently reported a significant excess of four-jet events at the LEP 1.5 and LEP 2. While not yet confirmed by the other collaborations, it was recently proposed that this excess may be explained by certain R-parity violating operators in supersymmetric models. R-parity violating operators introduce the danger of inducing rapid proton decay. I discuss how the operators required to explain the ALEPH four jet events may arise from superstring derived models without inducing rapid proton decay.
