and Excitations and the Quark Model
E. Klempt, V. Burkert, U. Thoma +2
The spectrum of and excitations is reviewed taking into account (nearly) all hyperon resonances which were seen in early analyses or in one of the recent partial-wave ana…
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…
A connection between angular dependent phase ambiguities and the uniqueness of the partial wave decomposition
A. Å varc, Y. Wunderlich, H. OsmanoviÄ +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…
Inclusion of electroproduction data in a coupled channel analysis
M. Mai, J. Hergenrather, M. Döring +4
Exclusive electroproduction reactions provide an access to the structure of excited baryons. To extract electroproduction multipoles encoding this information, the Jülich-Bonn-Was…
Precise Measurement of Sigma Beam Asymmetry for Positive Pion Photoproduction on the Proton from 800 to 1500 Mev
O. Bartalini, V. Bellini, J. -P. Bocquet +31
The Sigma beam asymmetry for positive pion photoproduction on the proton has been measured over an angular range of 40-170 deg at photon energies from 0.8 to 1.5 GeV. The resulting…
Multipole Analysis of Recent Pion Electroproduction Data
R. Arndt, W. Briscoe, I. Strakovsky +1
We have performed a series of global and single-Q2 fits to the growing database for pion electroproduction. We compare to some other recent fits which have used different formalism…
