Measurements of the inclusive pion electroproduction reaction e − +p → e − + π ± +X made at the Wilson Synchrotron Laboratory are reported. Data were taken at points with nominal ( Q 2 , W ) values of (0.6, 2.67), (1.2, 2.67), (2.0, 2.67) and (1.2, 2.15) in (GeV 2 , GeV). A more complete angular distribution was taken at (1.2, 2.67). The virtual photoproduction cross section for π + + missing mass is studied as a function of missing mass, Feynman scaling variables, Q 2 and W . The invariant cross section show a simple behavior as a function of Q 2 and W . Its dependenc on P ⊥ 2 , x ′ and φ is determined. |
