<u><b>James:</b></u> Updated asymmetries with new binning (doubled

widths). Work is in progress, but seems fine, overall.<br>

<u><b>Anusha:</b></u> Follow up to data/MC comparisons scaling models

(Form Factors, ...) and parameterizations. Previously done with carbon

target, now with NH3. <br>

<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Updates_on_01/04/2012-NH3/Use_Arrington_et._al_parame._and_scaling_up_MEC%2C_Form_Factor">https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Updates_on_01/04/2012-NH3/Use_Arrington_et._al_parame._and_scaling_up_MEC%2C_Form_Factor</a><br>

<br>

Obtained some preliminary elastic dilution factors.<br>

Will try to include aluminum windows.<br>

<br>

<br>

<u><b>Hovhannes:</b></u> 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.<br>

Will try with EPC. <br>

<u><b>Whit:</b></u> Posted rough draft of Hall C Users' Meeting talk,

giving update on BETA-asymmetries analysis.<br>

<br>

Working getting and identifying pions with his MC. The identification

involves comparing using conventional versus neural network.<br>

<br>

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

<u><b>Oscar/Narbe:</b></u> Studying effects of BETA-block acceptance

cuts for 4.7 GeV<br>

<br>

comparing MC<br>

<a class="moz-txt-link-freetext" href="https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/122111/">https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/122111/</a><br>

<br>

and data<br>

<a class="moz-txt-link-freetext" href="https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/010412/">https://userweb.jlab.org/~narbe/SANE/analysis/kinematics/acceptance/010412/</a><br>

<br>

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. <br>

<br>

<br>

As always, please let me know if I missed anything or if I made any

mistake(s).<br>

<br>

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