Abstract

A search for scalar top quarks in R-parity violating supersymmetry is performed in e+p collisions at HERA using the H1 detector. The data, taken at s=319GeV and 301 GeV, correspond to an integrated luminosity of 106pb-1. The resonant production of scalar top quarks t̃ in positron quark fusion via an R-parity violating Yukawa coupling λ′ is considered with the subsequent bosonic stop decay t̃→b̃W. The R-parity violating decay of the sbottom quark b̃→dν̄e and leptonic and hadronic W decays are considered. No evidence for stop production is found in the search for bosonic stop decays nor in a search for the direct R-parity violating decay t̃→eq. Mass dependent limits on λ′ are obtained in the framework of the minimal supersymmetric Standard Model. Stop quarks with masses up to 275GeV can be excluded at the 95% confidence level for a Yukawa coupling of electromagnetic strength.

N2 - A search for scalar top quarks in R-parity violating supersymmetry is performed in e+p collisions at HERA using the H1 detector. The data, taken at s=319GeV and 301 GeV, correspond to an integrated luminosity of 106pb-1. The resonant production of scalar top quarks t̃ in positron quark fusion via an R-parity violating Yukawa coupling λ′ is considered with the subsequent bosonic stop decay t̃→b̃W. The R-parity violating decay of the sbottom quark b̃→dν̄e and leptonic and hadronic W decays are considered. No evidence for stop production is found in the search for bosonic stop decays nor in a search for the direct R-parity violating decay t̃→eq. Mass dependent limits on λ′ are obtained in the framework of the minimal supersymmetric Standard Model. Stop quarks with masses up to 275GeV can be excluded at the 95% confidence level for a Yukawa coupling of electromagnetic strength.
