Experiment E06-009: Measurement of Longitudinal and Transverse Structure Functions on Deuterium in the Nucleon Resonance Region
Abstract
This experiment ran in Hall C at Jefferson Lab to measure L/T separated structure functions from deuterium from the quasielastic region through the nucleon resonance region and beyond (up to W^2=4.5 GeV^2), spanning the four-momentum transfer range 0.25 < Q^2 < 4.0 (GeV/c)^2 which is full Q^2 range for two running periods. ROSEN07, however, being the second period, focused on higher Q^2 range above 2 (GeV/c)^2. The Rosenbluth separation technique will be used to separate longitudinal and transverse cross sections to extract structure functions F1, F2, FL and R. This experiment is the second part of the first global survey of these fundamental quantities on deuterium which began with the Hall C experiment E02-109. The measurement of these fundamental quantities allows a variety of physics issues to be addressed, including: an evaluation of QCD moments of the deuteron and neutron structure functions, and quark-hadron duality in deuteron. This experiment was completed in july 2007 using the High Momentum Spectrometer to detect electrons from a 4 cm deuterium target. An overview will be presented of the experiment and analysis, along with preliminary results.
