Measurements of branching ratios for η decays into charged particles
Measurements of branching ratios for η decays into charged particles
The WASA-at-COSY experiment has collected 3×10^7 events with η mesons produced via the reaction pd→He3η at T=1.0GeV. Using this data set, we evaluate the branching ratios of the decays η→π+π−γ, η→e+e−γ, η→π+π−e+e−, and η→e+e−e+e−. The branching ratios are normalized to the η→π+π−π0 decay. In additio...

In addition an upper limit on a CP-violating asymmetry in η→π+π−e+e− is extracted. |
