We start by presenting physical arguments for the impossibility of perturbative thermalization leading to (non-viscous) Bjorken hydrodynamic description of heavy ion collisions. These arguments are complimentary to our more formal argument presented in [1]. We argue that the success of hydrodynamic models in describing the quark-gluon system produced in heavy ion collisions could only be due to...

Light front (LF) Hamiltonian operators for effective particles in quantum field theory (QFT) provide a new path toward understanding of hadronic structure and interactions. The origin of new thrust is a far reaching simplification of the approach in comparison to the standard form of dynamics: boosts are kinematical, instantaneous potentials can exist on the front hyperplane without contradicti...

Abstract. Relativistic heavy ion collisions produce thousands of particles, and it is sometimes difficult to believe that these processes allow for a theoretical description directly in terms of the underlying theory – QCD. However once the parton densities are sufficiently large, an essential simplification occurs – the dynamics becomes semi– classical. As a result, a simple ab initio approach...

Relations connecting various zero momentum correlators of interpolating fields for pseudoscalar and scalar channel, containing one heavy and one light quark field, are derived from the Euclidean space formulation of the QCD functional integral. These relations may serve as constraints on the phenomenological models or approaches motivated from QCD, and suggest a method to extract the chiral qua...

Quark deconfinement phase transition at finite temperature and density is investigated in the frame of quantum mechanics. By solving the Schrödinger equation for a heavy quark in a thermal mean field, we calculate the quark probability distribution as a function of temperature and density. The confined wave function in the vacuum expands outward rapidly when the temperature and density are high...
