A study of the centrally produced π0π0π0 channel in pp interactions at 450 GeV/ c

The reaction pp→ p f ( π 0 π 0 π 0) p s has been studied at 450 GeV/ c. The π 0 π 0 π 0 effective mass spectrum shows clear η(547) and π 2(1670) signals. Branching ratios for the η(547) and π 2(1670) are given as well as upper limits for the decays of the ω(782), a 1(1260) and a 2(1320) into 3 π 0....
