Profiling hot and dense nuclear medium with high transverse momentum hadrons produced in d+Au and Au+Au collisions by the PHENIX experiment at RHIC
PHENIX measurements of high transverse momentum (pT) identified hadrons in d+Au and Au+Au collisions are presented. The nuclear modification factors (RdA and RAA
Nearby in the stack
) for
π0
and
η
are found to be very consistent in both collision systems, respectively. Using large amount of
p+p
and Au+Au datasets, the fractional momentum loss (
Sloss
) and the path-length dependent yield of
π0
in Au+Au collisions are obtained. The hadron spectra in the most central
d
+Au and the most peripheral Au+Au collisions are studied. The spectra shapes are found to be similar in both systems, but the yield is suppressed in the most peripheral Au+Au collisions.
