Description

A search for a narrow baryonic resonance decaying to Ks0p or Ks0p-bar is carried out in deep inelastic ep scattering with the H1 detector at HERA. Such a resonance could be a strange pentaquark Θ+, evidence for which has been reported by several experiments. The Ks0p and Ks0p-bar invariant mass distributions presented here do not show any significant peak in the mass range from threshold up to 1.7 GeV. Mass dependent upper limits on σ(ep->eΘ+X)xBR(Θ+->K0p) are obtained at the 95% confidence level
