26 May 2003 | | Journal: | Phys.Lett. B566 (2003) 201-206 DOI: 10.1016/S0370-2693(03)00845-1 | | Subject: | hep-ph hep-th | | Affiliation: | CERN), Yitzhak Frishman (Weizmann Inst.), Marek Karliner (Tel-Aviv Univ. | | Abstract: | Extending earlier work on strong-coupling meson-baryon scattering in QCD_2, we derive the effective meson-baryon action for any value of the coupling constant, in the large-N_c limit. Colour degrees of freedom play an important role, and we show that meson-baryon scattering can be formulated as a relativistic potential problem. We distinguish two cases that are non-trivial for unequal quark masses, and present the resulting equations for meson-baryon scattering amplitudes. | | Source: | arXiv, hep-ph/0305292 | | Services: | Forum | Review | PDF | Favorites | |
