Abstract
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(-)pi(-)-->Lambdapi(-)pi(-)-->ppi(-)pi(-)pi(-). No evidence for a previously reported Xi(--)(1860) resonance is found in the Xi(-)pi(-) invariant mass spectrum. An upper limit for the photoproduction cross section of 2.1 nb is found at the 90% ...

Abstract
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(-)pi(-)-->Lambdapi(-)pi(-)-->ppi(-)pi(-)pi(-). No evidence for a previously reported Xi(--)(1860) resonance is found in the Xi(-)pi(-) 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(0)(1530) is found to be between 9 and 24 nb.
