Nuclear dependence of Drell-Yan and J/psi production in FNAL E866 Conference Paper uri icon


  • Fermilab E866 has measured the target-mass dependence of Drell-Yan and J/ dimuon production induced by an 800 GeV proton beam on targets of Be, Fe and W. Clear evidence of nuclear shadowing is observed in the Drell-Yan cross section ratios per nucleon at small x 2 . The x 1 dependence of the cross section ratios provides a determination of the energy loss of ultra-relativistic quarks as they pass through cold nuclei. Preliminary results for J/ yields show maximum cross section ratios that are slightly less than 1 at an x F value near 0.1. The yield on heavy targets is much more strongly suppressed relative to light targets at larger values of x F .
