Abstract

A search for squarks in R-parity violating supersymmetry is performed in e ^±p collisions at HERA using the HI detector. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of 64.3pb ^-1 for e ⁺p collisions and 13.5pb ^-1 for e ^-p collisions. The resonant production of squarks via a Yukawa coupling λ′ is considered, taking into account direct and indirect R-parity violating decay modes. No evidence for squark production is found in the multi-lepton and multi-jet final state topologies investigated. Mass dependent limits on λ′ are obtained in the framework of the Minimal Supersymmetric Standard Model. In addition, the results are interpreted in terms of constraints on the parameters of the minimal Supergravity model. At the 95 % confidence level squarks of all flavours with masses up to 275 GeV are excluded in a large part of the parameter space for a Yukawa coupling of electromagnetic strength. For a coupling strength 100 times smaller, masses up to 220 GeV can be ruled out.

N2 - A search for squarks in R-parity violating supersymmetry is performed in e ±p collisions at HERA using the HI detector. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of 64.3pb -1 for e +p collisions and 13.5pb -1 for e -p collisions. The resonant production of squarks via a Yukawa coupling λ′ is considered, taking into account direct and indirect R-parity violating decay modes. No evidence for squark production is found in the multi-lepton and multi-jet final state topologies investigated. Mass dependent limits on λ′ are obtained in the framework of the Minimal Supersymmetric Standard Model. In addition, the results are interpreted in terms of constraints on the parameters of the minimal Supergravity model. At the 95 % confidence level squarks of all flavours with masses up to 275 GeV are excluded in a large part of the parameter space for a Yukawa coupling of electromagnetic strength. For a coupling strength 100 times smaller, masses up to 220 GeV can be ruled out.
