Analysis of Meson-baryon Scattering Processes Related by Su(3) in a Unitarized Veneziano Model*
We extend a previously developed eikonal-like model to analyze meson-baryon scattering. Unitarity is partly described by introducing all the coupled two-particle channels which are related to each other by the requirements of SU(3), duality, factorization and absence of exotics 0 The Pomeron is interpreted as the manifestation of multiparticle unitarity rather than as a t-channel Regge exchange...
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 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 کاملDecuplet contribution to the meson-baryon scattering lengths
We calculate decuplet contributions to the s-wave pseudoscalar meson octet-baryon scattering lengths to the third order in heavy baryon chiral perturbation theory (HBχPT). Using experimental pion-nucleon and kaon-nucleon scattering lengths as inputs, we determine low-energy constants and predict other meson-baryon scattering lengths. Numerically we consider three cases: (1) the case with only b...
