| Abstract: | We present the analysis of three-particle correlation with respect to reaction system, transverse momentum (p
T
) of associated and trigger particles measured by STAR experiment at RHIC. Our preliminary results indicate presence of conical
emission of charge particles correlated with high p
T
trigger particles in central A+A collisions. The measured conical emission angle is independent of p
T
of associate hadrons, possibly consistent with Mach cone shock wave mechanism. The first result on PID three-particle correlation
with identified associated particles is also reported. |
