Hi,
below are the minutes of today's analysis meeting.
Minutes
-hPz for deuterium from d(e,e'p) (Adam)
+See ppt.
+Comparison of hPz from Arenhoevel-MC and hPz from super ratio
method. Super ratio method gives on the order of 5% smaller
hPz.
+Still, a Q2 dependence is seen. Q2Bin-tobin fluctuation seems to
become larger when accounting for the spin angle map in the super
ratio method (for each Q2bin, the yield-weighted average spin angle
is used). Not understood, exclude possible mistakes
+Should look at yields when asymmetries don't look plausible
+Discussion: Q2 dependence of hPz, even after accounting for spin
angle map, may be due to a spin angle profile along the target-z
coordinate. Therefore, hPz should be extracted as a function of z,
for each Q2bin.
-Deuteron photodisintegration (Tim)
+Progress report, see pdf.
+Deuteron photodisintegration: target-only asymmetries T20,T21,T22:
T21 crosses zero near 90 degree cm angle, only T20 and T22
are significant.
+T20 and T22 extraction. Comparison with Arenhoevel and data from
Russia
+MC required to study distribution of cm angles
+Pzz needs to be updated,
-Pion electroproduction from deuterium (Aki)
+See ppt
+Event selection, yields, asymmetries, comparison with hydrogen data
+Yields versus W for d(e,e'piplus)nn,d(e,e'p)pinulln,d(e,e'piminus)pp
+Tensor asymmetries (near threshold, these should show prominent
structure due to the isospin triplet state, this depends on
resolution)
+Need to compare to Pandharipande
-AOB
+Collaboration meeting next week on Friday, July 14, 2006. All
analysis reviews will be on that same day, there is no additional
pre-meeting.
+Agenda will come up soon
+Sasha to arrive on Monday
Best regards,
Michael
