Your main plots assume that the dominant background for eta —> B gamma with B —> gamma pi0 will be eta —> gamma gamma pi0. And on page 2 you say you estimate the size of all other backgrounds to be about 20% of the size of the eta —> gamma gamma pi0 background. How did you estimate this 20%? It might strengthen your case to add a description of how you made this estimation. Or if that estimation comes from other parts of the proposal, to refer the reader to the appropriate sections.</div><div><br></div><div>Ryan</div><div><br></div><div><br></div><div><br><div><div>On May 1, 2014, at 1:41 PM, Gan, Liping <<a href="mailto:ganl@uncw.edu">ganl@uncw.edu</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1"><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Dear colleagues,<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">The draft of experimental reach for B-boson search is posted at <a href="http://argus.phys.uregina.ca/gluex/DocDB/0024/002460/001/B-boson-exp.pdf">http://argus.phys.uregina.ca/gluex/DocDB/0024/002460/001/B-boson-exp.pdf</a> .
