摘要：

The cross section of the process e(+)e(-) -> omega pi(0)pi(0) is measured at nineteen center-of-mass energies from 2.0 to 3.08 GeV using data collected with the BESIII detector at the BEPCII storage ring. A resonant structure around 2.20 GeV is observed with statistical significance larger than 5 sigma. Using a coherent fit to the cross section line shape, the mass and width are determined to be M = 2222 +/- 7 +/- 2 MeV/c(2) and Gamma = 59 +/- 30 +/- 6 MeV, respectively, where the first uncertainties are statistical and the second ones are systematic.
