Ambiguities in the Partial-Wave Analysis of the Photoproduction of Pairs of Pseudoscalar Mesons
J. Guo, E. Barriga, K. Scheuer +8
Applying the technique of partial-wave analysis, there are cases where more than one set of underlying complex-valued amplitudes can describe the measured observables. These ambigu…

Upper Limit on the Photoproduction Cross Section of the Spin-Exotic
GlueX Collaboration, F. Afzal, C. S. Akondi +147
The spin-exotic hybrid meson is predicted to have a large decay rate to the final state. Using 76.6~pb of data collected with the GlueX detector, we…
