Further evidence for the decay mode $\phi \rightarrow \eta \gamma$ and measurement of the branching ratio $\Gamma(\phi \rightarrow \eta \gamma )/ \Gamma ( \phi \rightarrow$ total)

The reaction pi /sup -/p to eta phi has been studied at 1.8 GeV/c incident pion momentum in order to investigate the electromagnetic decay model phi to eta gamma . The authors observed (27+or-6) events, yielding a branching ratio Gamma ( phi to eta gamma )/ Gamma ( phi to total)=(7.3+1.9)%. The theo...
