Measurement of eta meson decays into lepton-antilepton pairs
WASA Collaboration, M. BerÅowski, Chr. Bargholtz +50
A search for rare lepton decays of the eta meson was performed using the WASA detector at CELSIUS. Two candidates for double Dalitz decay eta->e+e-e+e- events are reported with a b…

Measurement of the eta->pi+pi-e+e- decay branching ratio
WASA Collaboration, Chr. Bargholtz, M. Bashkanov +48
The reaction pd->3He eta at threshold was used to provide a clean source of eta mesons for decay studies with the WASA detector at CELSIUS. The branching ratio of the decay eta->pi…

The pp -> pp pi pi pi reaction channels in the threshold region
WASA Collaboration, C. Pauly, M. Jacewicz +42
The cross section for prompt neutral and charged three pion production in pp interactions was measured at excess energies in the range 160 - 217 MeV. That comprises the first measu…
