Abstract

We report measurements of the inclusive electroproduction reaction e + p --> e + pi+ + X for pions produced at 90 in the virtual-photon-proton center-of-mass system. Data are presented at the (W,Q^2) points (2.2 GeV, 1.2 GeV^2), (2.2,3.6), (2.65,1.2), (2.65,2.0), (2.65,2.8), (2.65, 3.6), (3.1, 1.2), and (3.1, 2.0). The invariant structure function is studied as a function of W, Q^2, x_T, p_T^2 , and the square of the invariant undetected mass.
