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…
Spatial interpretation of "compositeness" for finite-range potentials
Peter C. Bruns
We discuss the relation between the "compositeness" of an s-wave bound state, as derived from a related partial wave scattering amplitude, and the corresponding spatial probability…
Structure of resonances in a square well potential
Peter C. Bruns
We study the structure of resonances as derived from the exactly solvable Lippmann-Schwinger equation for a one-dimensional square well potential. Within this framework, we discuss…
Pion correlation functions in position space from chiral perturbation theory with resonance exchange
Peter C. Bruns
Explicit expressions for pion correlators are derived in position-space, employing Chiral Perturbation Theory (ChPT). Resonance exchange contributions are included to test the rang…
First moments of nucleon generalized parton distributions in chiral perturbation theory at full one-loop order
Philipp Wein, Peter C. Bruns, Andreas Schäfer
In this paper we present chiral extrapolation formulas for the generalized form factors connected to the first moments of chiral-even generalized parton distributions. For the desc…
