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…
Generalization of the model-independent Laurent-Pietarinen single-channel pole-extraction formalism to multiple channels
Alfred Svarc, Mirza Hadzimehmedovic, Hedim Osmanovic +3
A method to extract resonance pole information from single-channel partial-wave amplitudes based on a Laurent (Mittag-Leffler) expansion and conformal mapping techniques has recent…
Poles of Karlsruhe-Helsinki KH80 and KA84 solutions extracted by using Laurent+Pietarinen method
Alfred Svarc, Mirza Hadzimehmedovic, Rifat Omerovic +2
Poles of partial wave scattering matrices have also in hadron spectroscopy recently been established as a sole link between experiment and QCD theories and models [1-4]. We have, h…
PWA tools in Hadronic Spectroscopy
S. Ceci, M. Döring, E. Epple +21
The mini-proceedings of the Workshop on PWA tools in Hadronic Spectroscopy held in Mainz from February 18th to 20th, 2013.
A new method for extracting poles from single-channel data based on Laurent expansion of T-matrices with Pietarinen power series representing the non-singular part
Alfred Svarc, Mirza Hadzimehmedovic, Hedim Osmanovic +1
We present a new approach to quantifying pole parameters of single-channel processes based on Laurent expansion of partial wave T-matrices. Instead of guessing the analytical form…
