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.
