Experiment E06-009: Measurement of Longitudinal and Transverse Structure Functions on Deuterium in the Nucleon Resonance Region
ORAL
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 F$_{1}$, F$_{2}$, F$_{L}$ 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.
