psi and excess leptons in photoproduction
Description
The A-dependence of psi photoproduction was measured on beryllium and tantalum. From this are found sigma/sub psi N/ = 2.75 +- 0.90 mb. A study was made of excess leptons relative to pion production in photoproduction. A μ/π ratio of 1.40 +- 0.25 x 10-4 was found at 20 GeV incident photon energy. The energy dependence of psi photoproduction was determined and appeared to have a ''pseudo-threshold'' at 12 GeV
