[Sane-analysis] Minutes of January 5th Analysis Meeting

[Narbe Kalantarians]

_*James:*_ Updated asymmetries with new binning (doubled widths). Work 
is in progress, but seems fine, overall.

_*Anusha:*_ Follow up to data/MC comparisons scaling models (Form 
Factors, ...) and parameterizations. Previously done with carbon target, 
now with NH3.

Obtained some preliminary elastic dilution factors.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Dilution_Factor_from_NH3
Will try to include aluminum windows.


_*Hovhannes:*_ Working further on pi0/symmetric-pair background 
contribution. Noticed that generator used in MC for pi0 (Wiser) is per 
nucleon. Treating the integral of (MC) events with regard to this, the 
pi0 contribution would be more similar to the data.

Will try with EPC.


_*Whit:*_ Posted rough draft of Hall C Users' Meeting talk, giving 
update on BETA-asymmetries analysis.

Working getting and identifying pions with his MC. The identification 
involves comparing using conventional versus neural network.

Wrote a single-event display. Showing a good/representative ones.

_*Oscar/Narbe:*_ Studying effects of BETA-block acceptance cuts for 4.7 GeV

comparing MC
https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/122111/

and data
https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/010412/

The case for perpendicular seems to have some consistency for both data 
and MC. The case for parallel field doesn't quite so much, in that the 
data shows more fall-off with the acceptance cut.


As always, please let me know if I missed anything or if I made any 
mistake(s).

Next meeting will be January 11th at 3:30 pm (JLab time).
