The high-Q2 HERA anomaly and supersymmetric unification

We discuss an initial condition on the superpotential couplings of an SU(5) theory which allows the R-violating term LdcQ but avoids the simultaneous presence of LLec+dcdcuc. This same condition keeps under control the products of pairs of different coupling λijkLidjcQk, which are more strongly constrained by flavour-changing-neutral-current limits. In our view, this observation makes relatively more plausible the interpretation of the high-Q2 HERA anomaly, if real, as caused by squark production.
