Exotic Omega(0)(c) baryons from meson-baryon scattering

A meson-baryon interaction in the charm +1, strangeness 2 and isospin 0 sector is built from a t-channel vector meson exchange model employing effective Lagrangians. The implementation of coupled-channel unitarizat...

The impact of final-state interaction on the πΣ photoproduction in the Λ(1405) region

It was recently demonstrated that the meson-baryon rescattering in the final state has a major impact on the magnitude and structure of the πΣ mass distributions of this work emphasizing the model dependence of the meson-

S =-1 meson-baryon interaction and the role of isospin filtering processes

A study of the meson-baryon interaction in the S = -1 sector is performed at Jlab, or the weak decay of the Lambda(b) into a J/Psi and different meson-baryon would put valuable constraints on the chiral mo...

Chirally motivated K(-) nuclear potentials

In-medium subthreshold (K) over barN scattering amplitudes calculated within a chirally motivated meson-baryon coupled-channel model are used self consistently to confront K(-) atom data across the periodic table....

In-medium (K)over-bar- and eta-Meson Interactions and Bound States

The role played by subthreshold meson-baryon dynamics is demonstrated in K--atom, (K) over bar -nuclear and eta-nuclear bound-state calculations within in-medium models of (K) over barN and eta N interactions. New analyses ...

In-medium eta N interactions and eta nuclear bound states

The in-medium eta N interaction near and below threshold is constructed from a free-space chirally-inspired meson-baryon coupled-channel model that captures the physics of the N* (1535) baryon resonance. Nucleon Pa...

Kaonic hydrogen versus the K-p low energy data

We present an exact solution to the K --proton bound state problem formulated in the momentum space. The 1s level characteristics of the kaonic hydrogen are computed simultaneously with the available low energy K-p data. In the strong interaction...

The constraining effect of isospin filtering processes in low energy meson-baryon interactions

constraints on the chiral models describing the S = -1 meson-baryon interaction.Motivated by the recent precise SIDDHARTA measurement of the energy shift and width of kaonic hydrogen, we have revisited the theoretical stud...
