The Casimir Energy Paradox of the QCD String
K. Jimmy Juge🇨🇭 · Julius Kuti🇺🇸 · Colin Morningstar🇺🇸
It is widely thought that the early onset of the asymptotic Casimir energy with unit conformal charge signals bosonic string formation of the confining flux connecting a static quark-antiquark pair in QCD. This is observed on a scale where most of the string eigenmodes do not exist and the few stable modes above the ground state are displaced. Hints for the resolution of this paradox are suggested.
