摘要
HERA-B has searched in vain for evidence of the production of two recently reported states which have been identified as possible pentaquarks: the Theta(+)(1540). decaying into pK(3)(0), and the Xi(--)(3/2), decaying into Xi(-)pi(-). Upper limits on production cross sections at mid-rapidity and on ratios of the production cross sections to those of well-known resonances in 920 GeV proton-nucleus interactions are reported.
