Hello All,
<div class=""><br class="">
</div>
<div class="">I suspect the difference is probably GEMC 5.1+ vs 5.0. I don't know if the changes currently present in 5.1 are well-documented, but I do know that we were 100% sure that 5.0 was 100% consistent with 4.4.2, and I made sure of that.

I was quite surprised to see such a big difference going from "GEMC 4.4.2 + Coatjava 6.5.6.2" to "GEMC 5.1.0 + Coatjava 8.1.0"</div>

If I am not wrong, GEMC 5 has extensively validated wrt GEMC 4, maybe it has to do with the Coatjava version?</div>

Hi everyone,</div>
<p class="x_MsoNormal" style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;">
</p>
<div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
Attached are the slides I was planning to show this morning.</div>
<div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
I studied the particle efficiencies as a function of current for MC.</div>
<div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
In a previous study, we saw a quite large discrepancy between efficiencies extracted from data and MC produced on OSG.</div>
<div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
I redid this study with custom simulation ran on GEMC 4.4.2 and 5.1.0. It seems the latest leads to lower efficiencies, closer to the ones extracted from data. There is still some discrepancies however. I also noticed a large difference of proton efficiency
in the CD between both settings.</div>
<div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
Please let me know what you think and I am really keen on new ideas to proceed.</div>
