Observation of structure in p̄p → π0π0

Abstract We present a partial wave amplitude analysis of the differential cross sections for pp → π 0 π 0 at 25 energies from 2.12 to 2.43 GeV. The results suggest the presence of a J PC I G = 2 ++ 0 + resonance at 2.15 GeV. An isospin decomposition of pp → π + π - is also presented.
