| Abstract: | An analysis of data on is presented at beam momenta 600 to 1940 MeV/c. There is evidence for an I=1, JPC=2−+ resonance in ηηπ0 with mass M=1880±20 MeV and width 255±45 MeV, decaying strongly to a2(1320)η; it is too strong to be explained as the high mass tail of π2(1670)→a2(1320)η. There is tentative evidence also for weak decays to f0(1500)π. It makes a natural partner to the η2(1860). |
