Study of e^+ Production from π^0 Decay in Electron Scattering Experiments
Abstract
Inclusive scattering experiment studies of parton-hadron duality, F_2^N structure functions, measurements of R=σ_T/σL in nucleaon resonance region and measurment of the nuclear depedence of R have been performed in Hall C experimental end station at Jefferson Lab. The background reactions for the (e,e') experiments are e^- events from the e^+e^- pair production of π^0 decay. The experimental setup for inclusive scattering in Hall C allows for a second spectrometer, either the High Momentum Spectrometer (HMS) or the Short Orbit Spectrometer (SOS), to be used for e^+ detection. Currently, there exists a large database of e^+ data ranging in four-momentum tranfer squared from .5 GeV to 4 GeV. e^+/e^- ratios for several experiments will be presented and compared with existing e^+ models.
