Forward quark jet-nucleus scattering in a light-front Hamiltonian approach
Abstract
We investigate the scattering of a quark jet on a high-energy heavy nucleus using the time-dependent light-front Hamiltonian approach. We simulate a real-time evolution of the quark in a strong classical color field of the relativistic nucleus, described as the Color Glass Condensate. We study the sub-eikonal effect by letting the quark jet carry realistic finite longitudinal momenta, and we find sizeable changes on the transverse coordinate distribution of the quark. We also observe the energy loss of the quark through gluon emissions in the |q⟩+|qg⟩ Fock space. This approach provides us with an opportunity to study scattering processes from non-perturbative aspects.
