Measurement of the J/$$\Psi$$ Photoproduction Cross Section
- Center for Research and Advanced Studies of the National Polytechnic Institute, Mexico City (Mexico)
The elastic J /$$\Psi$$ photoproduction cross section on beryllium has been measured for photon energies up to 400 GeV. We discuss the experimental and analysis techniques used to obtain the sample of events and to calculate the cross section. Measurement of the energy dependence of the cross section is presented. The results are compared with data from previous experiments and with the predictions from current QCD models of J /$$\Psi$$ photoproduction. The presented data was taken from E-687 fixed target experiment at Fermilab in 1987 and at the beginning of 1988.
