Abstract:

Medium modification of dihadron fragmentation functions due to gluon bremsstrahlung induced by multiple scattering is studied in both deeply inelastic scattering (DIS) off large nuclei and high-energy heavy-ion collisions. The modified fragmentation functions for dihadrons are found to follow closely that of single hadrons leading to a weak nuclear suppression of their ratios as measured by HERMES in DIS experiments. Meanwhile, a moderate medium enhancement of the near-side correlation of two high

p_T

hadrons is found in central heavy-ion collisions, partially due to trigger bias caused by the competition between parton energy loss and the initial Cronin effect.
