As a quark and an antiquark cannot be isolated, the intrinsic motion of a
composite\(q\overline {q}\) system in its lowest-energy states lies predominantly in 1+ 1 …

Anomalous soft photons in excess of what is expected from electromagnetic bremsstrahlung
have been observed in association with the production of hadrons, mostly mesons, in high …

If we approximate light quarks as massless and apply the Schwinger confinement
mechanism to light quarks, we will reach the conclusion that a light quark q and its antiquark …

The requirement for the absence of spontaneous symmetry breaking in the d= 1 dimension
has been used to optimize the regulator dependence of functional renormalization group …

I discuss the two-flavor Schwinger model both without and with fermion masses. I argue that
the phenomenon of “conformal coalescence,” in unparticle physics in which linear …

We study the stability of a hypothetical QED neutron, which consists of a color-singlet system
of two d quarks and au quark interacting with the QED interaction. As a quark cannot be …

The scheme dependence of the renormalization group (RG) flow has been investigated in
the local potential approximation for two-dimensional periodic, sine-Gordon type field …

Known results on two-dimensional quantum electrodynamics (QED 2) have been used to
study the dependence of functional renormalization group equations on renormalization …

We aim to optimize the functional form of the compactly supported smooth (CSS) regulator
within the functional renormalization group (RG), in the framework of bosonized two …

The Schwinger confinement mechanism stipulates that a massless fermion and a massless
antifermion are confined as a massive boson when they interact in the Abelian QED …
