Title:

The Glueball spectrum in large-N QCD

Abstract:

The aim of this work is to employ lattice simulations to study the glueball spectrum in the large-N limit as a fundamental probe of confinement, and to verify theoretical predictions. A pure Yang-Mills lattice implementation was developed in-house, and used for computing the scalar 0++ glueball mass in SU(2) as a first step towards this goal.

Although we have successfully observed an upper limit to the mass for the 0++  glueball in lattice units, we were unable to directly determine its mass. This is due to the signal of the 2-point correlation function being too noisy in the current implementation.

In this presentation, the important theoretical aspects required for understanding these simulations are discussed, as well as our findings from these simulations.
