<div class="x_moz-cite-prefix">A next step could be to include particle identification in the simulation and reconstruction. There are many protons in the CD where particle ID is limited to the lower momentum range and a high momentum proton may be misidentified
as a K+ or a pi+ and is lost for the reaction in question. <br>

Please find very interesting results from Anna. I decided to send them in advance because of huge amount of really needed slides. She advanced her analysis essentially by implementing the presentation framework similar to the developed by FX. The outcome I
see:</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
-momentum dependent cuts for isolation of pi^0p events are needed;</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
-analysis of the kinematics correlations in the ep---->e'p' gamma gamma reaction allow us to develop the set of cuts useful for isolation of pi^0p events in real measurements with the contribution from pi^0p and other open channels, and apparatus background;</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
-event selection (in toy world with pi^0p channel only) in ep--->e'p' \gamma+X<br>
</div>
<div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
reaction increase the statistic more then factor of 10 in comparison with more exclusive ep--->e'p'\gamma\gamma +X selection. The problem Anna simulation is not able to address is the real background beneath exclusive peak in real world with all open exclusive
channels. <br>

<div>я попробовала повторить презентацию FX (несколько я все же не поняла).</div>
<div>Но получилось как-то.... много. Понимаю, что рассказывать все равно буду по сути, и на всем останавливаться совсем не нужно. Ну, в общем, посмотрите, мы тоже можем делать презентации с множеством графиков</div>
