Dynamical baryon resonances from chiral unitarity
A. Ramos, C. Bennhold, A. Hosaka +6
We report on the latests developments in the field of baryonic resonances generated from the meson-baryon interaction in coupled channels using a chiral unitary approach. The colle…
On the resonant and non-resonant contributions to B\toρπ
Jose A. Oller
We discuss the importance of the background in order to understand the scattering in the J^{PC}=0^{++} low and intermediate energy region and in particular regarding the σmeson. In…
Chiral dynamics and the reactions pp \to d K^+ \bar{K}^0 and pp \to d π^+ η
E. Oset, José A. Oller, Ulf-G. Meißner
We perform a study of the final state interactions of the K^+ \bar{K^0} and the \bar{K^0}d systems in the reactions pp \to d K^+ \bar{K^0} and pp \to d π^+ η. Since the two-meson s…
Scalar Mesons and Chiral Symmetry
J. A. Oller
It is the purpose of the present manuscript to emphasize those aspects that make the scalar sector with vacuum quantum numbers rather unique. Chiral symmetry is the basic tool for…
The phi --> pi^+ pi^- and phi radiative decays within a chiral unitary approach
E. Oset, S. Hirenzaki, E. Marco +3
We report on recent results on the decay of the phi into pi^+ pi^- and phi radiative decays into pi^0 pi^0 gamma and pi^0 eta gamma, which require the consideration of the final st…
A coupled channel unitary chiral approach to the meson-meson interaction and pion-pion scattering in a nuclear medium
E. Oset, J. A. Oller, J. R. Peláez +2
A new tool which combines chiral perturbation theory and unitarity in coupled channels is applied with success to the study of the meson-meson interaction, extending the theoretica…
