9 Nov 1998 | | Journal: | Phys.Rev. D61 (2000) 025017 | | Subject: | hep-th | | Abstract: | The unconstrained classical system equivalent to spatially homogeneous SU(2) Yang-Mills theory with theta angle is obtained and canonically quantized. The Schrödinger eigenvalue problem is solved approximately for the low lying states using variational calculation. The properties of the groundstate are discussed, in particular its electric and magnetic properties, and the value of the "gluon condensate" is calculated. Furthermore it is shown that the energy spectrum of SU(2) Yang-Mills quantum mechanics is independent of the theta angle. Explicit evaluation of the Witten formula for the topological susceptibility gives strong support for the consistency of the variational results obtained. | | Source: | arXiv, hep-th/9811070 | | Services: | Forum | Review | PDF | Favorites | |
