Observation of eta-c and other structures in the radiative decay psi to gamma eta pi-plus pi-minus
The Mark III detector at SPEAR was used to observe the exclusive radiative decay [...] A spin-parity analysis was performed to determine the quantum numbers of the resonances responsible for this structure. However, the result was seen to be model dependent, so that it was not possible to …

Eta photoproduction study with the upgraded Glasgow tagger at MAMI
Photoproduction of mesons provides an excellent means by which to study the proton excitation spectrum. The existence and properties of some nucleon resonances are well established, but many more are still debated, meriting much theoretical and experimental attention. The proximity and widths of …
