Dynamical renormalization group approach to the Altarelli-Parisi-Lipatov equations
D. Boyanovsky, H. J. de Vega, D. -S. Lee +2
The Altarelli-Parisi-Lipatov equations for the parton distribution functions are rederived using the dynamical renormalization group approach to quantum kinetics. This method syste…
The effective potential of composite fields in weakly coupled QED in a uniform external magnetic field
D. -S. Lee, P. N. McGraw, Y. J. Ng +1
The effective potential for the composite fields responsible for chiral symmetry breaking in weakly coupled QED in a magnetic field is derived. The global minimum of the effective…
Fermion Damping in a Fermion-Scalar Plasma
D. Boyanovsky, H. J. de Vega, Y. J. Ng +2
In this article we study the dynamics of fermions in a fermion-scalar plasma. We begin by obtaining the effective in-medium Dirac equation in real time which is fully renormalized…
Chiral symmetry breaking in a uniform external magnetic field II. Symmetry restoration at high temperatures and chemical potentials
D. -S. Lee, C. N. Leung, Y. J. Ng
Chiral symmetry is dynamically broken in quenched, ladder QED at weak gauge couplings when an external magnetic field is present. In this paper, we show that chiral symmetry is res…
