Spin Zero Glueballs in the Bethe-Salpeter Formalism
arXiv:1211.4648 · doi:10.1103/PhysRevD.87.036009
Abstract
The Schwinger-Dyson Bethe-Salpeter approach to the bound state problem is applied to the spin zero glueball spectrum. Although a moderately successful description of the two point functions and the glueball spectrum can be obtained, further work is required to reduce sensitivity to model truncations.
