Minutes of BRAHMSAnalysis Meeting Friday 28 August 2009 ======================================================= Call in 631-344-6261 Present: Flemming, Ramiro, JH, Chellis, Steve, Kris, Michael Agenda http://indico.cern.ch/conferenceDisplay.py?confId=67031 While waiting for everyone to come Steve reviewed Pawel's paper. He had some comments on the abstract and author list. The references also need to be cleaned up. Steve will get his comments on p/pi to Pawel and Ramiro will do some cleaning up. They hope to agree on the abstract by Monday. 09:30 p + p stopping Kris Hagel ======================================= Kris discussed how to get a stopping measurement from our net protons distributions. He has tried to copy the formalism from the AuAu paper which means he needs lambda/p and neutron/p ratios. STAR has measured the lambda/p ratio and for n/p he uses HIJING to get a rapidity dependent factor It was agreed that we should be including single diffractive events in HIJING. He is taking the lambda/p ratio to be independent of rapidity. He has used a Momguas distribution, constrained to end at y=ybeam to describe the data. JH thought that perhaps we should use PYTHIA. He also looked at the NA49 paper so that he could study the systematics of deltaY vs energy. We need to think about the systematic errors. For calculating delta Y we discussed the importance of baryon conservation. Chellis asked if delta y was sensitive to the n/p ratio since it seems somewhat high to him. AOB: ==== Michael talked to Selemon about his paper. He asked that he produce the dN/dy's from fits to individual spectra rather than the blast wave. We will compare the results next week. ===================== submitted by Michael Murray ======================== _______________________________________________ Brahms-l mailing list Brahms-l_at_lists.bnl.gov https://lists.bnl.gov/mailman/listinfo/brahms-lReceived on Fri Aug 28 2009 - 14:00:08 EDT
