Abstract
Systematic comparisons of jetlike correlation data to radiative and collisional energy loss model calculations are essential to extract transport properties of the quark-gluon medium created in relativistic heavy ion collisions. This paper presents a transport study of collisional broadening of jetlike correlations, by following parton-parton collision history in a multiphase transport (AMPT) model. The correlation shape is studied as a function of the number of parton-parton collisions suffered by a high transverse momentum probe parton () and the azimuth of the probe relative to the reaction plane (). Correlation is found to broaden with increasing and from in- to out-of-plane direction. This study provides a transport model reference for future jet-medium interaction studies.
