Y.Miake,
KPS meeting at Seju, 2004
26
Transverse momentum ditr.
lPID by high res. TOF.
lFlatter pt distr for heavier particle mass
lKnown as effects by collective expansion.
lProton dominance > 2 GeV/c, where the proton/pion ratio ~ 1
lincreases with centrality
lmost peripheral ~ ee/pp
lpeak(?) at 2-3 GeV/c
lfrag. process should show np> np as seen in ee/pp
lClear heavy ion effect
