Abstract

A search for narrow baryonic resonances decaying into Ξ ^-π^- or Ξ^-π⁺ and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon four-momentum transfer squared 2 < Q² < 100 GeV². No signal is observed for a new baryonic state in the mass range 1600-2300 MeV in either the doubly charged or the neutral decay channels. The known Ξ(1530)⁰ is observed through its decay mode into Ξ^-π⁺. Upper limits are given on the ratio of the production rates of new baryonic states, such as the hypothetical pentaquark states Ξ^- _5q or Ξ⁰ _5q, relative to the Ξ(1530)⁰ baryon state.

N2 - A search for narrow baryonic resonances decaying into Ξ -π- or Ξ-π+ and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon four-momentum transfer squared 2 < Q2 < 100 GeV2. No signal is observed for a new baryonic state in the mass range 1600-2300 MeV in either the doubly charged or the neutral decay channels. The known Ξ(1530)0 is observed through its decay mode into Ξ-π+. Upper limits are given on the ratio of the production rates of new baryonic states, such as the hypothetical pentaquark states Ξ- 5q or Ξ0 5q, relative to the Ξ(1530)0 baryon state.
