Abstract

An analysis of data on pbar-p -> eta-eta-pizero-pizero is presented at pbar beam momenta 600 to 1940 MeV/c. There is evidence for an I = 1, J^PC = 2^-+ resonance in eta-eta-pizero with mass M = 1880 +- 20 MeV and width 255 +- 45 MeV, decaying strongly a2(1320)-eta; it is too strong to be explained as the high mass tail of \pi_2(1670) -> a2(1320)-eta. There is tentative evidence also for weak decays to f_0(1500)\pi. It makes a natural partner to the eta 2(1860).
