| Abstract | A search for squarks in R-parity violating supersymmetry is performed in ep
collisions at HERA using the H1 detector. The full data sample available is
used for the analysis corresponding to an integrated luminosity of 438
pb^-1. The resonant production of squarks via a Yukawa-type coupling lambda'
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 at the 95% confidence level on lambda'_1j1 and lambda'_11k
(j,k=1,2,3) for all three squark generations are obtained in a
phenomenological Minimal Supersymmetric Standard Model. Additional
constraints on the universal mass parameters of sfermions and gauginos are
set in a minimal Supergravity Model assuming Radiative Electroweak Symmetry
Breaking given a specific value of the coupling lambda'. Finally the
dependence of the results on tan beta is studied. |
