Linear confinement and AdS/QCD

Abstract

In a theory with linear confinement, such as QCD, the masses squared ${m}_{n,S}^{2}$ of mesons with high spin $S$ or high radial excitation number $n$ are expected, from semiclassical arguments, to grow linearly with $S$ and $n$. We show that this behavior can be reproduced within a putative 5-dimensional theory holographically dual to QCD (AdS/QCD). With the assumption that such a dual theory exists and describes highly excited mesons as well, we show that an asymptotically linear ${m}^{2}$ spectrum translates into a strong constraint on the infrared behavior of that theory. In the simplest model which obeys such a constraint we find ${m}_{n,S}^{2}\ensuremath{\sim}(n+S)$.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
