dc.description.abstract | In this work we present predictions for meson-baryon molecules in the Ecc sector. The states are modelled as either pseudoscalar or vector mesons interacting with ground state baryons in s-wave, through a t-channel vector exchange picture described by effective Lagrangians. Unitarization is implemented using the Bethe-Salpeter equation, from which the molecules emerge as poles of the resulting scattering amplitude. As a result, we get a total of eight states. Four pseudoscalar-baryon states, with JP = 1=2-, at 3862, 4135, 4239, and 4240 MeV; and four vectorbaryon states, degenerate with JP = 1=2-; 3=2-, with masses of 4380, 4353, 4387 and 4523 MeV. | ca |
