In recent years light-cone quantization of quantum field theory has emerged as a promising
method for solving problems in the strong coupling regime. The approach has a number of …

This paper presents a new renormalization procedure for Hamiltonians such as those of light-
front field theory. The bare Hamiltonian with an arbitrarily large, but finite cutoff, is …

We examine the current state-of-the-art in nonperturbative calculations done with
Hamiltonians constructed in light-front quantization of various field theories. The language of …

In this work the determination of low-energy bound states in quantum chromodynamics is
recast so that it is linked to a weak-coupling problem. This allows one to approach the …

We study the heavy quarkonium within the basis light-front quantization approach. We
implement the one-gluon exchange interaction and a confining potential inspired by light …

More than twenty years after quantum chromodynamics (QCD) was introduced as a
microscopic theory of strong interactions, very little is known about its solutions. At least in …

An outstanding goal of physics is to find solutions that describe hadrons in the theory of
strong interactions, Quantum Chromodynamics (QCD). For this goal, the light-front …

It is shown how to modify the canonical light-front quantization of the (1+ 1)-dimensional sine-
Gordon model such that the zero-mode problem of light-front quantization is avoided. The …

We study the renormalization problem on the light front for the two-fermion bound state in the
(3+ 1)-dimensional Yukawa model, working within the lowest-order Tamm-Dancoff …

In the study of the decay of a heavy scalar particle at rest in the Yukawa model at the one-
and two-loop levels, it is shown explicitly that naive light-cone quantization leads to a …
