Based on the leading order term of the chiral Lagrangian a rich spectrum of molecules is generated, owing to final-state interactions. The spectrum of s- and d-wave baryon states with zero and non-zero charm is remarkably consistent with the empirical pattern. In particular, the recently announced Σc(2800) of the BELLE collaboration is reproduced with realistic mass and width parameters. Similarly, the dwave states Λc(2625) and Ξc(2815) are explained naturally as chiral excitations of JP = 3 2 + states. In the open-charm sector exotic multiplet structures are predicted. These findings support a radical conjecture: meson and baryon resonances that do not belong to the large-Nc ground state of QCD should be viewed as hadronic molecular states Kategória publikačnej činnosti ADC Číslo archívnej kópie 26410 Katal.org.

The regular part of the polarization operator is extracted from the realistic kaon-nucleon interaction based on the chiral and 1/N-c expansion. Contributions of Lambda(1116), Sigma(1195), Sigma*(1385) resonances are taken explicitly into account in the pole and regular terms with the inclusion of mean-field potentials. The baryon-baryon correlations are incorporated and fluctuation contributions are estimated. Results are applied for K- in neutron star matter. Within our model a second-order phase transition to the s-wave K- condensate state occurs at rho(c)greater than or similar to4rho(0) with baryon-baryon correlations included. We show that a second-order phase transition to the p-wave K- condensate state may occur at densities rho(c)similar to(3-5)rho(0) dependent on the parameter choice. We demonstrate that a first-order phase transition to a proton-enriched (approximately isospin-symmetric) nucleon matter with a p-wave K- condensate can occur at smaller densities, rholess than or similar to2rho(0). The transition is accompanied by the suppression of hyperon concentrations.
