Abstract
We discuss an initial condition on the superpotential couplings of an SU(5) theory which allows the R-violating term Ld(c)Q but avoids the simultaneous presence of LLe(c) d(c)d(c)u(c). This Same condition keeps under control the products of pairs of different couplings lambda(ijk)L(i)d(j)(c)Q(k), 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-Q(2) HERA anomaly, if real, as caused by squark production.
