Abstract

The dihadron spectra in high energy AA collisions are studied within the NLO pQCD parton model with jet quenching taken into account. The high pT dihadron spectra are found to be contributed not only by jet pairs close and tangential to the surface of the dense matter but also by punching-through jets survived at the center while the single hadron high pT spectra are only dominated by surface emission. Consequently, the suppression factor of such high-pT hadron pairs is found to be more sensitive to the initial gluon density than the single hadron suppression factor.
