Abstract

The reaction pp → p f (π0π0π0) ps has been studied at 450 GeV/c. The π0π0π0 effective mass spectrum shows clear η(547) and π2(1670) signals. Branching ratios for the η(547) and π2(1670) are given as well as upper limits for the decays of the ω(782), α1 (1260) and a2 (1320) into 3π0. © 2001 Published by Elsevier Science B.V
