We show that the recently measured asymmetry in helicity-angle spectra of the Λ-hyperons produced in the reaction pp→K + Λp reaction and the energy dependence of the total pp→K + Λp cross section can… (More)

Using a chiral unitary approach for the meson–baryon interactions, we show that two octets of J π = 1/2 − baryon states, which are degenerate in the limit of exact SU(3) symmetry, and a singlet are… (More)

The strong Kp scattering length is extracted within chiral SU(3) unitary approaches from a very large variety of fits to low-energy Kp scattering data. Very good overall agreement with available… (More)

We investigate strong and radiative meson decays in a generalized Nambu–Jona-Lasinio model. The one loop order calculation provides a satisfactory agreement with the data for the mesonic spectrum and… (More)

We develop a scheme for the extraction of the properties of the scalar mesons f0(600), f0(980), and a0(980) from lattice QCD data. This scheme is based on a two-channel chiral unitary approach with… (More)

A model of the DN interaction is presented which is developed in close analogy to the mesonexchange K̄N potential of the Jülich group utilizing SU(4) symmetry constraints. The main ingredients of the… (More)

A new method based on the concept of probability distribution is proposed to analyze the finite volume energy spectrum in lattice QCD. Using synthetic lattice data, we demonstrate that for the… (More)

Dynamical coupled-channel approaches are a widely used tool in hadronic physics that allow to analyze different reactions and partial waves in a consistent way. In such approaches the basic… (More)
