Single-energy partial wave analysis for pion photoproduction with fixed-t analyticity
H. Osmanović, M. Hadžimehmedović, R. Omerović +5
Experimental data for pion photoproduction including differential cross sections and various polarization observables from four reaction channels, , , $γ…
Dynamical generation of resonances in the P33 partial wave
B. Golli, H. Osmanović, S. Širca
We investigate the formation of resonances in the P33 partial wave with the emphasis on possible emergence of dynamically generated quasi-bound states as a consequence of a strong…
Single-Energy Partial Wave Analysis for Photoproduction on Proton with Fixed- Analyticity Imposed
H. Osmanović, M. Hadžimehmedović, R. Omerović +7
High precision data of the reaction from its threshold up to ~GeV have been used in order to perform a single-energy partial wave analysis with minimal model de…
The role of angle dependent phase rotations of reaction amplitudes in photoproduction on protons
A. Švarc, H. Osmanović, M. Hadžimehmedović +6
It has recently been proven that the invariance of observables with respect to angle dependent phase rotations of reaction amplitudes mixes multipoles changing also their relative…
Fixed-t analyticity as a constraint in single energy partial wave analyses of meson photoproduction reactions
H. Osmanović, M. Hadžimehmedović, R. Omerović +6
Partial wave amplitudes of meson photoproduction reactions are an important source of information in baryon spectroscopy. We investigate a new approach in single-energy partial wav…
A connection between angular dependent phase ambiguities and the uniqueness of the partial wave decomposition
A. Švarc, Y. Wunderlich, H. Osmanović +8
Unconstrained partial-wave amplitudes obtained at discrete energies from fits to complete sets of experimental data may not vary smoothly with energy, and are in principle non-uniq…
Baryon transition form factors at the pole
L. Tiator, M. Döring, R. L. Workman +5
Electromagnetic resonance properties are uniquely defined at the pole and do not depend on the separation of the resonance from background or the decay channel. Photon-nucleon bran…
Pole structure from energy-dependent and single-energy fits to elastic scattering data
Alfred Švarc, Mirza Hadžimehmedović, Hedim Osmanović +2
The pole structure of the current GW/SAID partial-wave analysis of elastic scattering and production data is studied. Pole positions and residues are extracted from both…
Pole positions and residues from pion photoproduction using the Laurent+Pietarinen expansion method
Alfred Švarc, Mirza Hadžimehmedović, Hedim Osmanović +3
We have applied a new approach to determine the pole positions and residues from pion photoproduction multipoles. The method is based on a Laurent expansion of the partial wave T-m…
Poles, the only true resonant-state signals, are extracted from a worldwide collection of partial wave amplitudes using only one, well controlled pole-extraction method
M. Hadžimehmedović, S. Ceci, A. Švarc +2
Each and every energy dependent partial-wave analysis is parameterizing the pole positions in a procedure defined by the way how the continuous energy dependence is implemented. Th…
