The tight knot spectrum in QCD

TL;DR

This paper models mesonic mass spectra in QCD using knotted flux tubes, predicting new states and fitting observed data with simple models.

Contribution

It introduces a novel approach of representing mesonic states as knotted chromoelectric flux tubes and predicts new states based on this model.

Findings

Fit observed mesonic spectra with one and two parameter models.

Predicts a new state at approximately 1190 MeV.

Suggests many new states above 1690 MeV.

Abstract

We model the observed $J^{++}$ mesonic mass spectrum in terms of energies for tightly knotted and linked chromoelectric QCD flux tubes. The data is fit with one and two parameter models. We predict a possible new state at approximately 1190 MeV and a plethora of new states above 1690 MeV.
