Inclusive π+ and π− distributions in electroproduction on protons

We investigate thes inclusive pion spectra in the electroproduction reaction ep → eπ±+ anything in a coincidence experiment at DESY. Data are presented from the kinematical region 0.1 < |q2| < 0.8 GeV2 and 3.15 < W < 2.8 GeV as a function of the transverse momentum squared pT2, the Feynman variable x2, and the azimuth angle φ. The charge ratio π+π− is given in terms of the variables q2 and x. The inclusive spectra are compared with results from photoproduction.
