Confinement, glueballs and strings from deformed AdS

Confinement, glueballs and strings from deformed AdS
Confinement, glueballs and strings from deformed AdS
We study aspects of confinement in two deformed versions of the AdS/CFT correspondence — the GPPZ dual of Script N = 1* Yang Mills, and the Yang Mills* Script N = 0 dual. Both geometries describe discrete glueball spectra which we calculate numerically. The results agree at the 10% level with previous AdS/CFT computations in the Klebanov Strassler background and AdS Schwarzchild respectively. We also calculate the spectra of bound states of the massive fermions in these geometries and show that they are light, so not decoupled from the dynamics. We then study the behaviour of Wilson loops in the 10d lifts of these geometries. We find a transition from AdS-like strings in the UV to strings that interact with the unknown physics of the central singularity of the space in the IR.

Abstract

We study aspects of confinement in two deformed versions of the AdS/CFT correspondence — the GPPZ dual of Script N = 1* Yang Mills, and the Yang Mills* Script N = 0 dual. Both geometries describe discrete glueball spectra which we calculate numerically. The results agree at the 10% level with previous AdS/CFT computations in the Klebanov Strassler background and AdS Schwarzchild respectively. We also calculate the spectra of bound states of the massive fermions in these geometries and show that they are light, so not decoupled from the dynamics. We then study the behaviour of Wilson loops in the 10d lifts of these geometries. We find a transition from AdS-like strings in the UV to strings that interact with the unknown physics of the central singularity of the space in the IR.
