Janus-Facedness of the Pion: Analytic Instantaneous Bethe-Salpeter Models
Wolfgang Lucha
TL;DR
This paper discusses a method to construct interaction potentials for light pseudoscalar mesons using analytic instantaneous Bethe-Salpeter models, revealing insights into their quark-antiquark bound state nature.
Contribution
It introduces an inversion technique to derive interaction potentials for pseudoscalar mesons within an analytic Bethe-Salpeter framework.
Findings
Potential functions can be constructed analytically for light pseudoscalar mesons.
The models support the Goldstone-boson nature of these mesons.
Inversion enables detailed understanding of meson-quark interactions.
Abstract
Inversion enables the construction of interaction potentials underlying - under fortunate circumstances even analytic - instantaneous Bethe-Salpeter descriptions of all lightest pseudoscalar mesons as quark-antiquark bound states of Goldstone-boson nature.
