SEARCH FOR EXCLUSIVE J / psi PRODUCTION

Chiang, I.H. ; Johnson, R.A. ; Kwan, B.P. ; et al.
Phys.Rev.D 34 (1986) 1619, 1986.
Inspire Record 228262 DOI 10.17182/hepdata.23503

We have searched for exclusive hadronic J/ψ production by looking for narrow resonances in the e+e− mass spectrum of the reaction π−p→e+e−n. No events were observed in the region around 3.1 GeV/c2. The cross section for the reaction π−p→J/ψ n at 13 GeV/c is no more than 103 pb at the 90% confidence level.

EXPERIMENTAL SEARCH FOR NARROW RESONANCES IN THE REACTION PI- P ---> GAMMA GAMMA N AT 13-GEV/C

Inspire Record 206508 DOI 10.17182/hepdata.30553

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/c 2 . For example, the 90% confidence limit on η c production is σ ( π − p→ η c n)× B ( η c → γγ ) < 44 pb.
