[Sane-analysis] DNP 2013 Abstract

Hello Everyone,

Here is my abstract:

Title: The Spin Asymmetries of the Nucleon Experiment

The Spin Asymmetries of the Nucleon Experiment (SANE)  measured the proton
spin structure function $g_2$ in a range of Bjorken $x$, $0.3 < x < 0.8$,
where extraction of the matrix element $d_2^p $ (an integral of $g_2$
weighted by $x^2$) is most sensitive.
The data was taken from $Q^2$ equal to $2.5 GeV^2$ up to $6.5 GeV^2$.
In this polarized electron scattering  off a polarized hydrogen target
experiment, two double spin asymmetries, $A_\parallel$ and $A_\perp$ were
measured using the BETA (Big Electron Telescope Array) Detector.
BETA consists of a scintillator hodoscope, gas Cherenkov, lucite hodoscope
and a large array of lead glass detectors.
With a unique open geometry, a threshold gas Cherenkov detector allowed
BETA to cleanly identify electrons for this inclusive experiment.
We will present the results of the measured asymmetries in addition to the
extraction of the virtual Compton scattering asymmetries and spin structure
functions.


Sorry for the short notice. Your comments are appreciated.

Cheers,
Whit
