Critical stability of few-body systems
V. A. Karmanov, J. Carbonell
When a two-body system is bound by a zero-range interaction, the corresponding three-body system -- considered in a non-relativistic framework -- collapses, that is its binding ene…
Present status of the Bethe-Salpeter approach in Minkowski space
V. A. Karmanov
Recently developed methods allowing to find the solutions of the Bethe-Salpeter equations in Minkowski space, both for the bound and scattering states, are reviewed. For the bound…
Nonperturbative calculations in truncated Fock space in LFD
V. A. Karmanov
A non-perturbative approach based on the Fock decomposition of the state vector and its truncation is discussed. In order the non-perturbative renormalization procedure after trunc…
Hadron structure and elastic scattering
I. M. Dremin
When colliding, the high energy hadrons can either produce new particles or scatter elastically without change of their quantum numbers and other particles produced. Namely elastic…
Transition electromagnetic form factor in the Minkowski space Bethe-Salpeter approach
J. Carbonell, V. A. Karmanov
Using the solutions of the Bethe-Salpeter equation in Minkowski space for bound and scattering states found in previous works, we calculate the transition electromagnetic form fact…
Bethe-Salpeter scattering amplitude in Minkowski space
J. Carbonell, V. A. Karmanov
The off-mass shell scattering amplitude, satisfying the Bethe-Salpeter equation for spinless particles in Minkowski space with the ladder kernel, is computed for the first time.
Light-Front Quantum Chromodynamics: A framework for the analysis of hadron physics
B. L. G. Bakker, A. Bassetto, S. J. Brodsky +17
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 Hamilto…
Proton periphery activated by multiparticle dynamics
I. M. Dremin, V. A. Nechitailo
It is shown that protons become more active at the periphery with increase of their collision energy. By computing the impact parameter distribution of the proton-proton overlap fu…
Interplay of total cross sections and ratios of real to imaginary parts of hadron amplitudes
I. M. Dremin
The impact of different assumptions about high energy behavior of the total cross section of proton-proton interactions on the ratio of the real to imaginary part of the forward el…
