Attending KD, VZ, RM, BF, NM, RF, ASUNH, PK, YX, MK, JC, OF, ASMIT;
CC, DH on speakerphone
-Collaboration meeting at Bates on Friday January 6, 2006 at 09:00am
-Extended analysis meeting at Bates either Wednesday January 4, 2006 9am
or Thursday January 5, 2006 9am.
!!PLEASE LET ME KNOW YOUR PREFERENCE!!
Where do we stand? Status of analyses in various channels
======================================================================
-Recrunch - MK
+Segmentation faults were due to scaler/epics problem.
CC fixed it, tagged v3_4_15
+Started 2005 recrunch on 12/13/2005, now in the 15100's,
~1400 runs to go = ~14 days
+Will identify and crunch crashed runs
+Update link directories ANALDIR and RECRUNCHDIR when ready
+2004: ~7000-13266; 2005: 14300-15214 by Christmas
+2005: 15214-16506 before January 6
+Will send notifying email
======================================================================
-Straight track analysis - CC, DH
+Started to set up confirmed runlist for -useful- cosmics runs
+Straight-track analysis essential to understand geometry
+DH preferring zero-field runs as more tracks come from the target
impacting perpendicularly into wire chamber
+CC cosmics lover as they relate the two sectors with each other
+Check of AM's wire calib by comparison of surveyed wire positions
should be pursued (KD), need to determine transformation between the two
coordinate frames, estimated a few days of uninterrupted work; precision
should be sufficient to resolve 0.1mm
======================================================================
-GEp/GMp - CC, ASUNH
+Paper drafted, presently reviewed by UNH group
+Concern about Q2 definition in two sectors -> kinematic correction;
observables (asymmetries) have strong Q2 dependence in each sector
+Q2 from averaging Q2(theta_e) and Q2(theta_p)
+More info on Q2 from time of flight
+T2D calibration
+Straight track analysis - geometry correction
+Energy loss correction for known particle IDs should be applied in
differential steps while refitting the track of known particle species
+Determine new kinematic corrections in the end
======================================================================
-GEp/GMp from d(e,e'p) - RF
+First extraction of R with super ratio method (see plots)
+Check statistical errors
+Recalculate hPz based on super ratio results
+Compare super ratio with Arenhoevel super ratio with and without FSI
+Extract GEp/GMp in the way it's done with GEn/GMn
======================================================================
-GEn - VZ, EG
+Showing new GEn 2004+2005 plot
+Wrong charge counting and missing events matters for FOM in 2005
+Extraction of GEn vs thetaCMS and vs pmiss
+Highest Q2 bin for 32 degree data: asymmetries negative
(thetastar=110deg), any diluting background would enhance GEn
+Highest Q2 bin for 45 degree data positive. In both datasets,
highest Q2 bin shows GEn enhancement over world data
+Rebin by combining the two highest bins
+Consistent with EG's analysis
======================================================================
-GMn - NM
+Arenhoevel calculation based on FW-parameterization ->3% change
+How many calculations based on FW are needed? I would suggest one
full kinematic grid based on FW for proton and neutron
->compare MC result based on FW with the one based on dipole
parameterization and Galster for GEn. Use this to correct MC predictions
based with GMn varied and proton ff's based on dipole.
+Update on kinematic corrections required
======================================================================
-AedV/AdT - RF, AD??
+AD starting ~mid January - 2005 data
======================================================================
-T11e - PK
+Changed binning, now three Q2 bins
+Data on T11e agrees well with Phillips
+Phillips disagrees with world data on A(Q2) up to 14%
+Therefore, extracted GM disagrees with Phillips
+Letter drafted, implement improvements
======================================================================
-T20/T21 - CZ
+Analysis "close to be finalized"
+Discussions with Dan Phillips on DeltaQd correction. Theories
diverge even more when Qd correct ... Q-dependence of DeltaQd
correction?
+MK to give seminar at Ohio University on January 10, 2006
======================================================================
-N-Delta inclusive - OF
+Polrad code working, needs to be implemented in BLASTMC.
+Should be compared with MASCARAD radiation tail + Maid2003
+Polrad without radiation in BLASTMC should agree with Maid2003 in
BLASTMC
======================================================================
-N-Delta exclusive - YX, ASMIT
+Implemented Maid2003 code agrees with Maid2003 from website
+Maid2003 based MC generator in place
+New UROP student working on kinematic corrections for pions
======================================================================
-(gamma,pn) - TS
+No report
======================================================================
-p(e,e'pi+n), d(e,e'pi+n) - TS
+No report
======================================================================
-d(e,e'ppi+) - CG
+No report
======================================================================
Best regards and merry Christmas to everybody.
