Comparison of π+ and π- Electroproduction at 0° and 90° Center-of-Mass Angles
Abstract
We report measurements of the ratio of positively charged to negatively charged pions electroproduced at 0° and 90° in the virtual photon-nucleon center-of-mass system. The π+π- ratio is studied as a function of W, Q2, ω, xT, and x in the range 2.1GeV<=W<=3.2GeV and 1.2GeV2<=Q2<=9.5GeV2.
