STAR Collaboration Meeting -- Spring 2015

(note: this blog entry posted few weeks after actual collaboration meeting)

Three talks given:
 - Junior's Day Talk on recent FMS results
 - FMS-RP correlations analysis update
 - Relative Luminosity Systematics

=========================================================================

Notes on Relative Luminosity systematics discussion

no question about using rate-safe method.. use it

understand spin pattern correlation with scaler A_LL
two hints:
  OOOOSSSS pattern has one sign scaler A_LL, SSSSOOOO has other sign
    --> stephen asks does pi0 A_LL correlate with this separation?
  removing n bXings after abort gaps causes the two peaks to merge and the
  correlation of spin pattern and scaler A_LL to disapear around 5 bXings

scott says we need to finalise a systematic for run12 before talking about run
13, since run12 is a nice gaussian scaler A_LL
  --> mean + mean uncertainty
  --> mean + rms/sqrt(N) (should be the same as above)
  --> overall mean + sigma (what I used for prelim A_LL)

compare ZDC A_N with cross-ratio method to that using ZDC rellum value
 -- maybe we could even do this with the vpd
