摘要

The Σ(1385) resonance, or Σ*, is well known as part of the standard baryon decuplet with spin J=32. Measurements of the reaction γp→K+Σ*0 are difficult to extract due to overlap with the nearby Λ(1405) resonance. However, the reaction γn→K+Σ *- has no overlap with the Λ(1405) due to its charge. Here we report the first measurement of cross sections and beam asymmetries for photoproduction of the Σ*- from a deuteron target. The cross sections at forward angles range from 0.4 to 1.2μb, with a broad maximum near Eγ 1.8GeV. The beam asymmetries are negative, in contrast with positive values for the γn→K+Σ- reaction.
