Exotic Ω c 0 baryons from meson-baryon scattering

A meson-baryon interaction in the charm +1, strangeness −2 and isospin 0 sector is built from a t-channel vector meson exchange model employing effective Lagrangians. The implementation of coupled-channel unitarization in the s-wave scattering amplitudes gives rise to two structures that have simila...

Summary:A meson-baryon interaction in the charm +1, strangeness −2 and isospin 0 sector is built from a t-channel vector meson exchange model employing effective Lagrangians. The implementation of coupled-channel unitarization in the s-wave scattering amplitudes gives rise to two structures that have similar masses and widths to those of the Ωc(3050)0 and Ωc(3090)0 states recently observed by the LHCb collaboration. A meson-baryon molecular interpretation of these resonances would assign their spin-parity to be JP = 1/2−.
