Hi g12,<br>So it seems no one else is looking at data below 3.6 GeV in g12. This is understandable as only the 3-prong trigger covered the entire tagging range. Please take a look at my thesis, specifically, Fig.4.24 on page 143. Notice the large jump in events seen in the data at 3.6 GeV. Coincidence? I think not but I can't prove it. There are three possible explanations for this jump:<br>
<br> 1. it is real physics<br> 2. gflux did not do an accurate job below 3.6 GeV<br> 3. the trigger efficiency between the 3 prong and production triggers is different and was not taken into account anywhere (gsim? gflux? gpp?)<br>
<br>My instinct points me to #3 above but I'm not sure what is to be done about it. I can not take much more time before I have to defend so I am looking for some scaling factor and an a plausible explanation.<br><br>
Thank you,<br><br clear="all"><br>-- <br>Johann Goetz<br><a href="mailto:jgoetz@ucla.edu">jgoetz@ucla.edu</a><br>UCLA Dept. Physics & Astronomy<br>Nefkens Group<br>
