Subject: New STAR Paper on <pt> Fluctuations


| Dear Tom, Bill, Flemming, and Wit,
| 
| I am pleased to announce STAR's intention to submit a new
| paper on "Event-by-event <pt> fluctuations in Au-Au
| collisions at roots_NN = 130 GeV" to Physical Review
| Letters one week from today. The title and abstract for
| the paper are enclosed.
| 
|               Sincerely,
| 
|               Tim

| Event-by-event <pt> fluctuations in Au-Au
| collisions at roots_NN = 130 GeV
| 
| We present the first large-acceptance measurement of
| event-wise <pt> fluctuations in Au-Au collisions at
| roots_NN = 130 GeV. Significant nonstatistical
| fluctuations are observed. The measured fractional
| r.m.s. width excess of the event-wise <pt>
| distribution for the 15% most-central events for
| charged hadrons within abs(eta) < 1 and
| 0.15 .le. pt .le 2 GeV/c is 13.7 +/- 0.1(stat) +/-
| 1.3(syst)% relative to a statistical reference.
| The variation of charge independent fluctuation
| excess with centrality is non-monotonic but smooth.
| Charge-dependent nonstatistical fluctuations are
| also observed.
