Aspects of Strangeness −1 Meson-Baryon Scattering
We consider meson-baryon interactions in S-wave with strangeness −1. This is a sector populated by plenty of resonances interacting in several two-body coupled channels. We consider a large set of experimental data, where the recent experiments are remarkably accurate. This requires a sound theoretical description to account for all the data and we employ Unitary Chiral Perturbation Theory up t...
متن کاملPseudoscalar Meson and Charmed Baryon Scattering Lengths
Up to now many heavy hadrons have been discovered experimentally. Their inner structures and interactions attract much attention. Some of them are speculated to be possible new hadron states beyond the traditional quark model. For example, the newly discovered Zb states are treated as the B̄ (∗)B∗ molecular states [1, 2]. Many other molecular states, such as those composed of ΞcΞc, DD̄ ∗, are als...
متن کاملOn the Strangeness −1 S-wave Meson-Baryon Scattering
We consider meson-baryon interactions in S-wave with strangeness −1. This is a nonperturbative sector populated by plenty of resonances interacting in several two-body coupled channels. We study this sector combining a large set of experimental data. The recent experiments are remarkably accurate demanding a sound theoretical description to account for all the data. We employ unitary chiral per...
متن کاملChiral unitary meson–baryon dynamics in the presence of resonances: Elastic pion–nucleon scattering
We develop a novel approach to chiral meson–baryon dynamics incorporating unitarity constraints and explicit resonance fields. It is based on the most general structure of any pion-nucleon partial wave amplitude neglecting the unphysical cuts as derived from theN/D method. This amplitude is then matched to the one–loop heavy baryon chiral perturbation theory result at third order and to tree le...
متن کاملProbing internucleus potential with large-angle quasi-elastic scattering
Recent measurements for fusion cross section at energies around the Coulomb barrier have systematically indicated a significant deviation of fusion cross sections from a prediction of double-folding model. It has been argued that the deviation can be accounted for if one uses a large value of surface diffuseness parameter for a Woods-Saxon internuclear potential. We investigate this problem usi...
