Solving the Bethe-Salpeter equation for bound states of scalar theories in Minkowski space
Kensuke Kusaka, Ken Simpson, Anthony G. Williams
We apply the perturbation theory integral representation (PTIR) to solve for the bound state Bethe-Salpeter (BS) vertex for an arbitrary scattering kernel, without the need for any…
Covariant Solutions of the Bethe-Salpeter Equation
A. G. Williams, K. Kusaka, K. M. Simpson
There is a need for covariant solutions of bound state equations in order to construct realistic QCD based models of mesons and baryons. Furthermore, we ideally need to know the st…
Solving the Bethe-Salpeter Equation in Minkowski Space: Scalar Theories and Beyond
K. Kusaka, K. M. Simpson, A. G. Williams
The Bethe-Salpeter equation (BSE) for bound states in scalar theories is reformulated and solved in terms of a generalized spectral representation directly in Minkowski space. This…
SOLVING THE BETHE--SALPETER EQUATION IN MINKOWSKI SPACE: SCALAR THEORIES
Kensuke Kusaka, Anthony G. Williams
The Bethe-Salpeter (BS) equation for scalar-scalar bound states in scalar theories without derivative coupling is formulated and solved in Minkowski space. This is achieved using t…
Dyson-Schwinger equations and their application to nonperturbative field theory
F. T. Hawes, K. Kusaka, A. G. Williams
Two examples of recent progress in applications of the Dyson-Schwinger equation (DSE) formalism are presented: (1) Strong coupling quantum electrodynamics in 4 dimensions (QED)…
