Investigation of Pionic Contribution in the Lepton and Antilepton Production Cross Section in p-Cu and p-Pt Collision

Figure 5

(a) and (b) show ⁶³Cu and ¹⁹⁵Pt structure functions per nucleon in mean . The full curve is obtained by considering, the Fermi motion, the binding energy, and the pionic contribution effect. The dashed line shows the structure function by considering the Fermi motion and the binding energy. Experimental data shows deuterium structure function per nucleon [19].
