The decays of and resonances into , and final states are studied in a coupled-channel analysis of data on pion- and photo-induced reactions. Improvements…
Photoproduction of two charged pions off protons in the resonance region
A. V. Sarantsev, E. Klempt, K. V. Nikonov +4
Photoproduction of charged pions pairs off protons is studied within the invariant masses of the final state hadrons from 1.6 to 2.4 GeV at the Thomas Jefferson National Accelerato…
Measurement of the helicity asymmetry for the reaction in the resonance region
K. Chan, N. Zachariou, M. Bashkanov +9
The double-spin-polarization observable for has been measured with the CEBAF Large Acceptance Spectrometer (CLAS) at photon beam energies …
Note on the definitions of branching ratios of overlapping resonances
V. Burkert, V. Crede, E. Klempt +8
Branching ratios for the decay of hadrons with large width or near thresholds depend on their definition. We test different definitions and show that rather different branching rat…
Polarization observables in double neutral pion photoproduction
TAPS Collaboration, T. Seifen, J. Hartmann +73
Measurements of target asymmetries and double-polarization observables for the reaction are reported. The data were taken with the CBELSA/TAPS experiment at the ELS…

Data on the beam asymmetry in the photoproduction of mesons off protons are reported for tagged photon energies from 1130 to 1790 MeV (mass range from 1748 MeV to …
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…
Eta and Etaprime Photoproduction on the Nucleon with the Isobar Model EtaMAID2018
L. Tiator, M. Gorchtein, V. L. Kashevarov +7
The isobar model EtaMAID has been updated with new and high precision data for eta and etaprime photoproduction on protons and neutrons from MAMI, ELSA, GRAAL and CLAS. The backgro…
From Experimental Data to Pole Parameters in a Direct Way (Angle Dependent Continuum Ambiguity and Laurent + Pietarinen Expansion)
A. Švarc, Y. Wunderlich, H. Osmanović +8
Unconstrained partial-wave amplitudes obtained at discrete energies from fits to complete sets of eight independent observables which are required to uniquely reconstruct reaction…
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…
