A variation on "compositeness" (including higher partial waves)

Peter C. Bruns

The ``spatial interpretation of compositeness'', presented and discussed in [1,2] in the context of non-relativistic potential scattering, is extended to higher partial waves. A pa…

Constraining the chirally motivated - models with the photoproduction mass spectra

A. Cieply, P. C. Bruns

The paper presents a first time attempt on a combined fit of the low-energy data and the photoproduction mass spectra, performed without fixing the meson-baryon resca…

Testing chiral unitary models for the in photoproduction

P. C. Bruns, A. Cieplý, M. Mai

We adopt a novel formalism for the low-energy analysis of the photoproduction reaction to calculate the invariant mass distributions in the resonanc…

A toy model for "elementariness"

Peter C. Bruns

Motivated by recent efforts to analyze corrections to Weinberg's relations for the scattering length and effective range in the presence of a near-threshold bound state, we play ar…

SU(3) flavor symmetry considerations for the coupled channels system

P. C. Bruns, A. Cieplý

We study the impact of SU(3) flavor symmetry breaking on the properties of dynamically generated states within an effective separable potential model describing the coupled c…

A formalism for the study of photoproduction in the region

Peter C. Bruns

We present a formalism for the low-energy analysis of the photoproduction reaction in the resonance region. In particular, the constraints…
