Parton distribution functions from scalar light-front parton gas model
Shaoyang Jia, James P. Vary
We propose an application of a microcanonical ensemble with light-front kinematics to model the phase-space distribution of relativistic constituents of a bound state. These consti…
Erratum: Exact solutions to the fermion propagator Schwinger-Dyson equation in Minkowski space with on-shell renormalization for quenched QED \newline [Phys. Rev. D 96, 036021 (2017)]
Shaoyang Jia, Michael R. Pennington
With the introduction of a spectral representation, the Schwinger--Dyson equation (SDE) for the fermion propagator is formulated in Minkowski space in QED. After imposing the on-sh…
Formulating Schwinger--Dyson equations for QED propagators in Minkowski space
Shaoyang Jia
The Schwinger--Dyson equations (SDEs) are coupled integral equations for the Green's functions of a quantum field theory (QFT). The SDE approach is the analytic nonperturbative met…
Nakanishi integral representation of pseudoscalar fermion-antifermion bound states in the Bethe--Salpeter equation
Shaoyang Jia
We propose a method to solve for the pseudoscalar bound state amplitude of a fermion and an antifermion from its Bethe--Salpeter equation (BSE) in the Minkowski space applying spec…
