Analyticity Constraints for Hadron Amplitudes: Going High to Heal Low Energy Issues
JPAC Collaboration, V. Mathieu, J. Nys +7
Analyticity constitutes a rigid constraint on hadron scattering amplitudes. This property is used to relate models in different energy regimes. Using meson photoproduction as a ben…

Beam normal spin asymmetry for the process
Carl E. Carlson, Barbara Pasquini, Vladyslav Pauk +1
We calculate the single spin asymmetry for the process, for an electron beam polarized normal to the scattering plane. Such single spin asymmetries vanish in th…

New analysis of tensor resonances measured at the COMPASS experiment
A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232
We present a new amplitude analysis of the -wave in measured by COMPASS. Employing an analytical model based on the principles of the relativistic -mat…
