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…
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…
