Measurements of Hydrogen and Deuterium Inclusive Resonance Cross Sections at Intermediate Q$^{2}$ for Parton-Hadron Duality Studies.

ORAL

Abstract

Results from the Jefferson Lab E00-116 experiment that ran in Summer of 2003 will be presented. The experiment extended to higher Q$^{2}$ the precision measurements of inclusive nucleon resonance electroproduction cross sections from hydrogen and deuterium targets. The data cover a kinematic range of (3.9 -- 7.2) GeV$^{2}$ in Q$^{2}$ and (0.5 -- 0.9) in x, and will be used in conjunction with the elastic and inelastic data for precision experimental tests of parton-hadron (Bloom-Gilman) duality in the structure functions. E00-116 data that access the high x region will also be used to constrain higher moments of the structure functions and to extract matrix elements of higher-twist operators. This data will also provide a constraint for the F$_{2}^{d}$/F$_{2}^{p}$ ratio and therefore possibly be of utility in reducing the uncertainties on pdf curves at high x.
