<div dir="ltr">Dear all
<div><br>
</div>
<div>As a follow up from Friday's meeting, Anna agreed to provide me with her eppi0 simulation files so I can take a look with my code</div>
<div><br>
</div>
<div>I posted some slides summarizing my findings on the docDB page here</div>
<div><a href="https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=637">https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=637</a></div>
<div><br>
</div>
<div>I think that most of the background Anna observed comes from photons generated by the electron bremsstrahlung</div>
<div>One can mostly remove all this background with a simple cut on the angle between electron and photon > 7 degrees</div>
<div>The generated kinematics indicates that such a cut should be fine</div>
<div><br>
</div>
<div>In addition I applied a set of exclusivity cuts similar to what I used for the deep pi0 selection</div>
<div>Note that the values of these cuts should be adjusted for the analysis of the data, but overall I expect they would help clean up the backgrounds from other reactions as well</div>
<div><br>
</div>
<div>In general it seems prudent to remove photons around the electron direction, unless one is directly interested in bremsstrahlung events</div>
<div><br>
</div>
<div>Best regards</div>
<div>FX</div>
