The molecular nature of some exotic hadrons
A. Ramos, A. Feijoo, Q. Llorens +1
The exciting discovery by LHCb of the and pentaquarks, or the suggestion of a tetraquark nature for the state seen at BESIII and Belle, have…
The decay and the higher order chiral terms of the meson baryon interaction
A. Feijoo, V. K. Magas, A. Ramos +1
We study the weak decay of the into and states, and relate these processes to the decay mode. The elementary weak transitio…
The reaction in coupled channel chiral models up to next-to-leading order
V. K. Magas, A. Feijoo, A. Ramos
We study the meson-baryon interaction in S-wave in the strangeness S=-1 sector using a chiral unitary approach based on a next-to-leading order chiral SU(3) Lagrangian. We fit our…
Effects of the next-to-leading order terms in the chiral SU(3) Lagrangian on the strangeness -1 s-wave meson-baryon interactions
V. K. Magas, A. Feijoo, A. Ramos
The meson-baryon interactions in s-wave in the strangeness S=-1 sector are studied using a chiral unitarity approach based on the next-to-leading order chiral SU(3) Lagrangian. The…
On the nature of the Lambda(1405) as a superposition of two states
E. Oset, V. K. Magas, Ramos
We use recent data on the reaction with the mass distribution of forming the with a peak at 1420 MeV and a relatively narrow width of $Γ…
