High-pT hadrons in heavy ion collisions: from RHIC to LHC
Original language description
The length scale l p for production of leading hadrons in high- pT jets, constrained by energy conservation, is rather short and does not rise with pT . Therefore, the dominant source of suppression of high-pT single hadrons is attenuation of the produced colorless dipoles in the dense matter created in heavy ion collisions, rather than the induced energy loss at the short early stage of hadronization. Since the evolution of the initially small dipole size up to the hadron dimension is slowed down by Lorentz time dilation, the dipole survival probability rises with pT in a good accord with LHC data. The pT dependence of RAA at the energies of RHIC is weaker due to closeness of the kinematic bound. This description is parameter free, except the absorption rate of the medium, which is the goal of this analysis and is adjusted to data. The maximal value of the coordinate- and time-dependent transport coefficient q is found to be q0 = 0.30 - 0.45 GeV2 / fm at s = 62 - 200 GeV; and q0 = 0.6
