A Measurement of g2p and the Longitudinal-Transverse Spin Polarizability
Spokesmen: A. Camsonne, J.P. Chen, D. Crabb , K. Slifer (contact)
Jefferson Lab has been at the forefront of a
program to measure the nucleon
spin-dependent structure functions over a wide kinematic range. Data
of unprecedented quality has been extracted in all three experimental halls.
Higher moments of these quantities have proven to be powerful tools to test
QCD sum rules and will provide benchmark tests of Lattice QCD and Chiral Perturbation Theory. Precision measurements of gn1,2 and gp1 have been
performed as part of th...

Scintillator trigger efficiency
University of Regina, CANADA
for the Hall A collaboration
(thank you to E. Brash, S. Dumalski, M. Jones, R. Roche, L. Todor)
This talk is closely related to data analysis of the E89028 experiment
which consist of D(e,e'p)n and H(e,e'p) data sets taken at =
0.4, 1.0 and 1.6 .
Two types of inefficiency discussed here:
1) absolute inefficiency can be result of scattering between (in) the S1
and S2 scintillator planes. Some events therefore can miss S2 plane causing
absolute trigger inefficiency. GEANT model of HRS was used to
estimate the inefficiency value as a function of momentum of
detected particles (protons in our case).
2) S1 or S2 detector inefficiency due to insufficie...
