Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Selected Highlights from the Moments Discussions W.J. Llope for the attendees 5/24/2012 Thanks very much to the speakers and attendees for the lively and very interesting discussions! This is not a “summary” of the workshop so far. Many important details are of course available in the talks…

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Cebra R1,R2,R3= 1 if no critical behavior or if entirely critical behavior R4,R5= 0

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Koch “p” is generally rather small. Study moments with different “p” values… Wider cuts might introduce other effects (PID, backgrounds, e,y dependence)

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Koch Light nucleus integrated yield ratios….. d/(pp), t/(dp), He 3 /(dp) Effect lives at low P T, can signal survive our spallation cut?

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Stephanov Lattice rules out  B crit < 200 MeV General consensus that  B crit < 500 MeV

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Koch & Stephanov “can bend back over”

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Stephanov  B crit > , 11.5, and 7.7 (  B = 100 MeV in Athanasiou et al.) peak/|trough| ~30 at most, but can be a lot smaller

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Bellwied ….not really “moments,” but generated lots of discussion….

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ EXPERIMENTAL will not attempt to show all of the results…. I concentrate on pointing out track cuts… event cuts… bad-run & bad-event rejection… and then 1-2 “major results” plots from each talk…

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Sahoo (net-charge) background cut: refmult vs tofmatch only…. should stop using Run , use Run instead…

Moments Summary Click to edit Master subtitle style STAR Topical Workshop on Fluctuations & PID, Rice University, 5/24/ Big Picture (My View) Tremendous progress. Beautiful results. All should be congratulated on their hard work. However, some big differences in the analyses… Some bad-run and bad-event rejection criteria are v. loose, some are v. tight… refmult2corr (|  |<0.5) vs refmult3corr (|y|<0.5)… Gary- CBW correction weight? Nihar- spallation cut? multivariate background rejection? Daniel- QA run11 200? numerical stability? Xiaofeng- |Zvtx| 7.7? tighter background rejection? data/skellam tight RM cut? Lizhu- bad-event cut bands? Order of bad-run/evt/trk cuts? b-dep. of rejected evts? Evan- implementation? Sigma-field is isospin blind: “net-” moments vs “total-” moments?
