Studies of the reaction π - p→ η ' π 0 n at 38 and 100 GeV/c
Abstract
The production of η ' π 0 system in π - p charge-exchange interactions at π - momenta 38 GeV/c and 100 GeV/c has been studied. The 2γ and η π 0 π 0 decay modes of η ' leading to 4γ and 8γ final states respectively have been detected. No statistically significant peak is observed in the η ' π 0 mass spectrum in the range of 1.2 GeV÷2.1 GeV. An upper limit of 6·10-3 has been established for the a {2/0}(1320)→ η ' π 0 branching ratio.
