Abstract
High pT single and dihadron production is studied within a NLO pQCD parton model with jet quenching in high energy A + A collisions at RHIC/LHC energy. A simultaneous χ2-fit to both single and dihadron spectra can be achieved within a narrow range of the energy loss parameter. Punch-through jets are found to result in a dihadron suppression factor slightly more sensitive to medium properties than the single hadron suppression factor at RHIC. Such jets at LHC are found to dominate high pT dihadron production and the resulting dihadron spectra are more sensitive to the initial parton distribution functions than the single hadron spectra.
