Subject: abstract for April APS meeting<br>
Dear Deep Processes group,<br>
<br>
I would like to submit the following abstract for the April
APS meeting in<br>
Baltimore. Please let me know if you have any comments or
suggestions.<br>
<br>
Measurements of the cos\phi and cos2\phi moments of the
semi-inclusive<br>
deep inelastic scattering (SIDIS) cross-section were
performed. The data<br>
set used was the E1-f run from the CEBAF Large Acceptance
Spectrometer<br>
(CLAS) at Jefferson Lab which ran in 2003. The run used a
5.498 GeV<br>
longitudinally polarized electron beam and an unpolarized
liquid hydrogen<br>
target. Two pion channels (\pi+ and \pi-) were studied over
a broad<br>
kinematical range (x = 0.1 - 0.6, Q^2 = 1.0 - 4.5 GeV^2, z =
0.0 - 1.0,<br>
and P_T = 0.0 - 1.0 GeV). These measurements give insights
into the<br>
transverse momentum dependence of parton distribution
functions (PDFs)<br>
which describe the dynamics of quarks and gluons inside of
the proton.<br>
<br>
Thanks in advance for your feedback.<br>
<br>
Best regards,<br>
Nathan<br>
