  1. π+/p NA22 e+/e- AMY E735 UA1 OPAL HBT in pp collisions? Just a sampling • Dowell., Proc. Of the VII Topical Workshop on Proton-AntiProton Collider Physics, p115, Word Scientific 1989. • Lindsey. “Results from E735 at the Tevetron Proton-AntiProton Collider with root s= 1.8TeV”, Presented at the Quarkmatter 1991, Gatlinberg, Tennessee, Nov 11-15, 1991. • OPAL Collaboration. Physics Letters B. Vol 267 #1, 5 September, 1991. • NA22 Collaboration “Estimation of Hydrodynamical model parameters from the invariant spectrum and the Bose-Einstein Corrilations…”, Nijmegen preprint, HEN-405, Dec. 97. fm p/pbar

  2. Centrality dependence of Rout/Rside 0.2<kT<2.0GeV/c ,　<kT>=0.46GeV/c

  3. HBT dN/dt  ~ 2 fm/c Blast-wave type fits 0~8-9 fm/c time F. Retière, QM04; F. Retière & MAL nucl-th/0312024 “BlastWave” fits • Hydro (blast wave) • Input Short emission time • Multiplicity • Flow • Hbt

  4. Almond shape overlap region incoordinate space Pressure? “elliptic flow” barometer Origin:spatial anisotropy of the system when created, followed by multiple scattering of particles in the evolving system spatial anisotropy  momentum anisotropy v2:2nd harmonic Fourier coefficient in azimuthal distribution of particles with respect to the reaction plane
