(3+ 1)-dimensional light-front model with spontaneous breaking of chiral symmetry
(American Physical Society, 1997)We investigate a (3+ 1)-dimensional toy model that exhibits spontaneous breakdown of chiral symmetry, both in a light-front (LF) Hamiltonian and in a Euclidean Schwinger-Dyson (SD) formulation. We show that both formulations ... -
A 3+1 Dimensional LF Model with Spontaneous χ SB
(Springer, Berlin, Heidelberg, 1998)Light-front (LF) quantization provides an intuitive (physical basis!) description of hadron structure that stays close to the relevant degrees of freedom in high energy scattering: many high-energy scattering processes ... -
