Hard physics at STAR
- 10 Downloads
Preliminary results for the production of high transverse momentum hadrons are reported from the STAR detector at the Relativistic Heavy Ion Collider. Negative hadron spectra for 2 < pT < 6 (GeV/c) indicate a suppressed yield compared to expectations from \(p\bar p\) collisions at similar energy. The elliptical flow deviates from agreement with predictions based on purely hydrodynamical considerations at pT > 1.5 GeV/c. An initial measurement of the flavor dependence of baryon production at pT ≤ 2.25 GeV/c is also presented and discussed.
