Comments on Baryon Transition Form Factors
Christoph Hanhart, Maxim Mai, Ulf-G. Meißner +1
We discuss in rather general terms the properties of space-like baryon transition form factors. In particular, we argue why these are necessarily complex-valued, what can be deduce…
Polarization Observables and in the Reaction at CLAS
H. Jiang, S. Strauch, I. I. Strakovsky +3
Pion photoproduction in the reaction has been measured in the FROST experiment at the Thomas Jefferson National Accelerator Facility.…
Nature of the states from compositeness criteria
Yu-Fei Wang, Chao-Wei Shen, Deborah Rönchen +3
Based on a coupled-channel approach, we investigate the structures of four states through compositeness criteria. Toward a more precise description of the states, we have obt…
Jülich-Bonn-Washington Model for Pion Electroproduction Multipoles
Maxim Mai, Michael Döring, Carlos Granados +5
Pion electroproduction off the proton is analyzed in a new framework based on a general parametrization of transition amplitudes, including constraints from gauge invariance and th…
