Abstract

Narrow Ξ ^-π ^± and Ξ ⁺π ^± resonances produced by quasi-real photons have been searched for by the COMPASS experiment at CERN. The study was stimulated by the recent observation of an exotic baryonic state decaying into Ξ ^-π ⁺, at a mass of 1862 MeV, interpreted as a pentaquark. While the ordinary hyperon states Ξ (1530) ⁰ and Ξ(1530) ⁰ are clearly seen, no exotic baryon is observed in the data taken in 2002 and 2003.

N2 - Narrow Ξ -π ± and Ξ +π ± resonances produced by quasi-real photons have been searched for by the COMPASS experiment at CERN. The study was stimulated by the recent observation of an exotic baryonic state decaying into Ξ -π +, at a mass of 1862 MeV, interpreted as a pentaquark. While the ordinary hyperon states Ξ (1530) 0 and Ξ(1530) 0 are clearly seen, no exotic baryon is observed in the data taken in 2002 and 2003.
