Experiment: Differential Photoproduction Cross Sections of the Λ(1520), 2013

Spokespersons: R. A. Schumacher

Experiment comment: All known corrections were applied to the yield extraction, normalization, and acceptance calculations in these data. The given error bars are essentially statistical but include the fit uncertainties assiciated with background subtraction. The overall systematic uncertainty in these results was estimated to be 11.6%.
