Searches for the pentaquark states {xi}(1860){sup 0} and {xi}(1860){sup --} in neutron-carbon interactions via the EXCHARM experiment

Results of searches for the pentaquark states {xi}(1860){sup 0} and {xi}(1860){sup --} in neutron-carbon interactions at an average neutron energy of about 51 GeV via the EXCHARM experiment are presented. No such states are found in the {xi}{sup -}{pi}{sup +} and {xi}{sup -}{pi}{sup -} effective-mas...

Zusammenfassung:	Results of searches for the pentaquark states {xi}(1860){sup 0} and {xi}(1860){sup --} in neutron-carbon interactions at an average neutron energy of about 51 GeV via the EXCHARM experiment are presented. No such states are found in the {xi}{sup -}{pi}{sup +} and {xi}{sup -}{pi}{sup -} effective-mass spectra examined in this study. Upper limits on the cross sections for {xi}(1860){sup 0} and {xi}(1860){sup --} production are estimated.
