| Title: | Meson resonances, large N_c and chiral symmetry |
Authors: | Cirigliano, Vincenzo; Pich, Antonio CSIC ORCID; Ecker, Gerhard; Neufeld, Helmut | Keywords: | Chiral lagrangians 1/N Expansion QCD |
Issue Date: | 13-Jun-2003 | Publisher: | Institute of Physics Publishing | Citation: | Journal of High Energy Physics (6): 012 (2003) | Abstract: | We investigate the implications of large N_c and chiral symmetry for the mass spectra of meson resonances. Unlike for most other mesons, the mass matrix of the light scalars deviates strongly from its large-N_c limit. We discuss the possible assignments for the lightest scalar nonet that survives in the large-N_c limit. | Description: | 14 páginas, 2 tablas.-- arXiv:hep-ph/0305311v1 | Publisher version (URL): | http://dx.doi.org/10.1088/1126-6708/2003/06/012 | URI: | http://hdl.handle.net/10261/33125 | DOI: | 10.1088/1126-6708/2003/06/012 | ISSN: | 1126-6708 |
