17 Mar 1997 | | Journal: | Int.J.Mod.Phys. A12 (1997) 5305-5324 | | Subject: | hep-th hep-ph | | Affiliation: | Syracuse U.), Joseph Schechter (Syracuse U. | | Abstract: | We revisit the treatment of the multiflavor massive Schwinger model by non-Abelian Bosonization. We compare three different approximations to the low-lying spectrum: i) reading it off from the bosonized Lagrangian (neglecting interactions), ii) semi-classical quantization of the static soliton, iii) approximate semi-classical quantization of the ``breather’’ solitons. A number of new points are made in this process. We also suggest a different ``effective low-energy Lagrangian’’ for the theory which permits easy calculation of the low-energy scattering amplitudes. It correlates an exact mass formula of the system with the requirement of the Mermin-Wagner theorem. | | Source: | arXiv, hep-th/9703120 | | Services: | Forum | Review | PDF | Favorites | |
