Search for an exotic S =-2, Q =-2 baryon resonance at a mass near 1862 MeV in quasireal photoproduction

A search for an exotic baryon resonance with S=-2, Q=-2 has been performed in quasireal photoproduction on a deuterium target through the decay channel {xi}{sup -}{pi}{sup -}{yields}{lambda}{pi}{sup -}{pi}{sup -}{yields}p{pi}{sup -}{pi}{sup -}{pi}{sup -}. No evidence for a previously reported {xi}{sup --}(1860) resonance is found in the {xi}{sup -}{pi}{sup -} invariant mass spectrum. An upper limit for the photoproduction cross section of 2.1 nb is found at the 90% confidence level. The photoproduction cross section for the {xi}{sup 0}(1530) is found to be between 9 and 24 nb.
