PPT Slide
- Integrated pt spectrum assuming
?1. isotropic fireball ?(development in progress )
? 2. feed-down from the resonance & higher mass mesons.
we observe rho,omega,Kshort play the important role to the pi+ multiplicity, and
generate the pair decay spectrum for rho and Kshort
(1/pt dN/dpt distribution with the arbitrary normalization.)
- These plots are generated with the 3 different reconstruction efficiencies.
This will be equivalent to changing the selection cuts for tracks and studying the pt
spectral shape assuming the primary multiplicity and the kinematics are correct
( also we need to assume perfect tracking )
- Kinematic distributions is affected by the hydrodynamic motion and it's likely to be
included in the next release.
- In fact this will be of importance to the high pt particle ( pt > 2 GeV/c ),
where description by the perturbative physics can be claimed.
