Seminar

The tight knot spectrum in quantum chromodynamics

Kephart, T (Vanderbilt University)

Seminar Room 1, Newton Institute

Abstract

In 1867 Lord Kelvin suggested that elementary particles can be knotted fluid vortices in the aether. While his idea was revolutionary for his time, our present experimental knowledge does not agree with his conjecture. Nevertheless, the idea is attractive for its simplicity of relating fundamental physical and mathematical objects. In that spirit we model the observed J^{++} mesonic mass spectrum in terms of energies for tightly knotted and linked chromoelectric QCD flux tubes. The data is fitted with one and two parameter models. We predict one new state at 1200 MeV and a plethora of new states above 1700 MeV.
