Search for direct photon production at Fermilab energies and comparison with direct photon measurements at ISR energies
Description
A search for direct photon production has been performed at Fermilab in 200 and 300 GeV/c proton-Be interactions over a wide range of X/sub F/ and P/sub perpendicular to/. An excess of photons has been detected which when interpreted as single photon production yields a γ/π0 ratio which averages .070 +- .025 in the region 1.5 < p/sub perpendicular to/ < 4.0 GeV/c and -.7 < X/sub F/ < .0. This measurement is discussed and a comparison of this result with the ISR measurements of the γ/π0 ratio has been made in an attempt to infer the energy dependence of direct photon production
