Parton Energy Loss in the Generalized High-Twist Approach
نویسندگان
چکیده
We calculate the radiative parton energy loss in deeply inelastic scattering (DIS) off a large nucleus within generalized high-twist approach. The final gluon radiation spectrum is convolution of hard partonic part and transverse momentum dependent (TMD) quark-gluon correlation function, without twist expansion initial gluons used original high TMD function can be factorized approximately as product quark distribution which to define or jet transport coefficient. will recover Gylassy-Levai-Vitev (GLV) result first order opacity expansion, under static center soft approximation. also investigate numerically difference approximation,

Helicity-dependent Twist-two and Twist-three Generalized Parton Distributions in Light-Front QCD
We investigate the helicity dependent twist-two and twist-three generalized parton distributions in light-front Hamiltonian QCD for a massive dressed quark target. Working in the kinematical region ξ < x < 1, we obtain the splitting functions for the evolutions of twist-two quark and gluon distributions in a straightforward way. For the twist-three distribution, we find that all contributions a...
متن کاملA Parton-Hadron Cascade Approach in High-energy Nuclear Collisions
Event generators based on perturbative QCD (pQCD) are proposed such as HIJING (Heavy Ion Jet Interaction Generator)[1], VNI (Vincent Le Cucurullo Con Giginello)[2], in order to describe ultra-relativistic heavy ion collisions, especially, at collider energies (RHIC/LHC). Although both models reproduce many pp and p̄p data, there are large discrepancies in AA collisions between these two models, ...
متن کاملParton Energy Loss Without Transverse Momentum Broadening
The Jewel 1.0 Monte Carlo simulates jet evolution in a medium with a microscopic description of splitting and scattering processes. In the framework of this model we investigate the transverse momentum broadening due to medium effects in different scenarios. Depending on assumptions about hadronisation, we observe either a small increase or even a slight decrease of the mean transverse momentum...
متن کاملParton energy loss with detailed balance.
Stimulated gluon emission and thermal absorption, in addition to induced radiation, are considered for an energetic parton propagating inside a quark-gluon plasma. In the presence of thermal gluons, stimulated emission reduces, while absorption increases, the parton's energy. The net effect is a reduction of the parton energy loss. Though decreasing asymptotically as T/E with the parton energy,...
