On the Relation between the Slopes of Diffraction Cone in Single Diffraction Dissociation and Elastic Scattering
The fundamental relation betwen the slopes of diffraction cone in single diffraction dissociation and elastic scattering has been derived. PACS numbers: 11.80.-m, 13.85.-t, 21.30.+y
متن کاملAspects 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 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 کاملElastic meson production and Compton scattering 1
I discuss recent progress in the theory of exclusive meson production and Compton scattering, focusing on hard-scattering factorization and on the dipole formalism.
