[Sane-analysis] Abstract for the APS meeting.

[anusha at jlab.org]

Hi all,
 i am sending the abstract which is i am going to submit for the upcoming
APS meeting.
could you please let me know the comments by tomorrow morning.

and also, i have one more question.
do we need to submit our abstract individually or all SANE abstracts are
submitting by one person?

"Measurement of the proton electric to magnetic form factor ratio with
polarized target at high momentum transfer"

Experiment E07-003 (SANE, Spin Asymmetries of the Nucleon Experiment)
has been carried out in Hall C at Jefferson Lab to study the proton spin
structure functions with a dynamically polarized ammonia target and
longitudinally polarized electron beam. Scattered electrons were detected
by a large-acceptance calorimeter, while elastically recoiling protons
were simultaneously detected with high resolution with the high-momentum
spectrometer HMS. Analysis of the HMS data allows to extract the proton
electric to magnetic form factor ratio at high momentum transfer,
$Q^2$ = 5.25 and 6.25 (GeV/c)$^2$, from the double spin asymmetry.
As such, it allows to independently verify the falling of the form factor
ratio with increasing momentum transfer observed in previous polarization
transfer measurements.
Details and status of the analysis will be presented.
