Abstract:
A search for stop production in R-parity-violating supersymmetry has been performed in e+p interactions with the ZEUS detector at HERA, using an integrated luminosity of 65 pb-1. At HERA, the R-parity-violating coupling λ’ allows resonant squark production, e^+d->\bar(q) . Since the lowest-mass squark state in most supersymmetry models is the light stop, this search concentrated on production of , followed either by a direct R-parity-violating decay, or by the gauge decay. No evidence for stop production was found and limits were set on λ’131 as a function of the stop mass in the framework of the minimal supersymmetric standard model. The results have also been interpreted in terms of constraints on the parameters of the minimal supergravity model.
