Hi,
below are the minutes of today's analysis meeting.
The next meeting will be the BLAST collaboration meeting on Friday
11/17/2006 at 09:00am at Bates.

Minutes:
-d(e,e'p) kinematic corrections (AD)
+see ppt
+showing comparison of data-MC before and after applying EG's
corrections. Generally, the original discrepancies become much
smaller, in particular in the intermediate Q2 region where they were
sizable.
+Comparisons shown for p_e, theta_e, p_p, theta_p, for different Q2
bins. Corrections larger for momenta, angles less affected.
+Comparison shown for theta_q for various electron angle bins
->would need to see this also for Q2 bins
+While corrections from elastic scattering obviously work quite well
for quasielastic (e,e'p), there are also discrepancies left that will
be adressed with a refined kinematic correction using the
quasielastic MC.
-d(e,e'n) status update (EG,VZ)
+Discrepancies in runlist, charge, and raw asymmetries between EG and
VZ removed. Found and repaired two bugs, both analyses now
consistent
+Also MC asymmetries are now consistent betwee VZ and EG
+Extracted preliminary GEn for 2004 and 2005 and for the
combination. Results are pending on timing corrections.
+Timing corrections for the neutron-TOF determined for 2004 data,
by comparing measured neutron-TOF with calculated TOF from electron
angle and momentum and neutron angle. They are small!!
-> check yield comparison data-MC versus pmiss components for each
Q2bin without and with new corrections
+Analysis update with timing corrections in progress.
+Even better corrections are expected with corrections for
quasielastic scattering (right now only EG's elastic corrections are
applied for the electron)
-p(e,e')delta status analysis/results (OF)
+shown yields, asymmetries versus W for narrow slices of Q2
+Q2 so far limited to <0.18 (GeV/c)^2, but acceptance (with Cerenkov)
covers up to Q2=0.35
-> show asymmetries for higher Q2 bins as well at collaboration
meeting
-> as asymmetries vary slowly with Q2, choose wider bins
0.08-1.15, 0.15-0.22. 0.22-0.29, 0.29-0.35
-> justify this assumption by taking a narrow slice of W=1230+-20
and plot yields and asymmetry versus Q2
+Agreement between data and MC too good to be believable
+Amount of radiative tail in ELRADGEN-MC seems low compared to
unradiated elastic yield in the peak
-aob
+Expect referee report of proton PRL soon (see status below)
+Meeting on new experiment E06 for J-PARC/Japan this Saturday
11/04/2006 09:00 (all day) on campus (Kolker room)
