           Search for squark production in R-parity-violating
                          interactions at HERA

Squarks produced via an R-parity violating interaction in e^+p
collisions at a centre-of-mass energy of 300 GeV have been sought
with the ZEUS detector at HERA. Squarks produced in e^+ quark fusion
could decay to e-quark or gaugino-quark via a supersymmetric
gauge decay, resulting in a final state with multiple jets and
a lepton that could be a neutrino, e^+ or e^-.
No evidence for squark production was found and limits 
were set on the R-parity violating coupling as a function of the 
squark mass and the SUSY parameters \mu and M_2.
