Experimental estimate of the gluon structure function of the pion from J/Ψ production
Abstract
In experiment WA11, preformed at the CERN Super Proton Synchroton, we have determined the shape of the gluon structure function of the pion to be (1-x1)1.9+/-0.3 from the longitudinal momentum distribution of 38000 J/Ψ produced by the collisions of negative pions of momentum 190 GeV/c with beryllium.
