Abstract

Using a double arm electromagnetic calorimeter we have searched for narrow states produced in the exclusive reaction π^-p→γγn at 13 GeV/c. No enhancements were observed in the mass range 2.0-4.0 GeV/c². For example, the 90% confidence limit on η_c production is σ(π^-p→η_cn)× B(η_c→γγ) < 44 pb.
