Energy momentum tensor on and off the light cone: exposition with scalar Yukawa theory
Xianghui Cao, Siqi Xu, Yang Li +4
We compute the gravitational form factors , and of the scalar Yukawa theory using both the light-cone and covariant perturbation theory at the one-loop level.…
Abnormal solutions of Bethe--Salpeter equation with massless and massive exchanges
Jaume Carbonell1, Vladimir Karmanov, Ekaterina Kupriyanova +1
We summarize the main properties of the so called ''abnormal solutions'' of the Wick--Cutkosky model, i.e. two massive scalar particles interacting via massless scalar exchange ("p…
Abnormal states with unequal constituent masses
V. A. Karmanov
The Bethe-Salpeter equation for system of two oppositely charged particles not only reproduces the Coulomb spectrum, but, for enough large coupling constant , p…
Systems Dominated by Exchange Particles
V. A. Karmanov
As well known, the spectrum of a non-relativistic two-body system interacting by the Coulomb potential is the Balmer series produced by the Schrödinger equa…
Abnormal Bound Systems
V. A. Karmanov
It is taken for granted that bound systems are made of massive constituents that interact through particle exchanges (charged particles interacting via photon exchanges, quarks in…
New form of kernel in equation for Nakanishi function
V. A. Karmanov
The Bethe-Salpeter amplitude is expressed, by means of the Nakanishi integral representation, via a smooth function . This function satisfies a canonical equation…
