Overview
abstract
A search for pentaquarks decaying to -- (-+) and corresponding antiparticles has been performed with the ZEUS detector at HERA. The data sample consists of deep inelastic ep scattering events at centre-of-mass energies of 300 and 318 GeV, and corresponds to 121 pb -1 of integrated luminosity. A clear signal for 0(1530) -+ was observed. However, no signal for any new baryonic state was observed at higher masses in either the -- or -+ channels. The searches in the antiparticle channels were also negative. Upper limits on the ratio of a possible 3/2 - (3/20) signal to the 0(1530) signal were set in the mass range 1650-2350 MeV. 2005 Elsevier B.V. All rights reserved.
