Phenomenology of strong interactions: towards an effective theory for low energy QCD

In this paper, we develop models applicable to phenomenological particle physics by using the string analogy of particles. These theories can be used to investigate the phenomenology of confinement, deconfinement, chiral condensate, QGP phase transitions, and even the evolution of the early universe. Other confining properties such as scalar glueball mass, gluon mass, glueball-meson mixing states, QCD vacuum, and color superconductivity can also be investigated in these model frameworks. We use one of the models to describe the phenomenon of color confinement among glueballs at the end of the paper. The models are built based on the Dirac-Born-Infeld (DBI) action modified for open strings with their endpoints on a Dp-brane or brane-anti-brane at a tachyonic vacuum.

Automated summary

This paper develops models for phenomenological particle physics based on the string analogy of particles. These models can be used to investigate various phenomenological aspects, including confinement, deconfinement, chiral condensate, QGP phase transitions, and the evolution of the early universe. Additionally, properties such as scalar glueball mass, gluon mass, glueball-meson mixing states, QCD vacuum, and color superconductivity can also be explored using these model frameworks. The paper concludes by using one of the models to describe the phenomenon of color confinement among glueballs. These models are built upon the modified Dirac-Born-Infeld (DBI) action for open strings with endpoints on a Dp-brane or brane-anti-brane at a tachyonic vacuum.
