Abstract
We apply a multiphase transport (AMPT) model to study two-particle angular correlations in collisions at . In addition to being able to describe the angular correlation functions of meson-meson pairs, a large improvement for the angular correlations of baryon-baryon and antibaryon-antibaryon is achieved. We further find that the AMPT model with new quark coalescence provides an even better description on the anticorrelation feature of baryon-baryon correlations observed in the experiments. We also extend the study to -Pb collisions at and obtained similar results. These results help us better understand the particle production mechanism in and -Pb collisions at Large Hadron Collider energies.
