Nonstrange partner of strangeonium-like state Y(2175)

Inspired by the observed Y(2175) state, we predict its nonstrange partner Y(1915), which has a resonance structure with mass around 1915 MeV and width about 317-354 MeV. Experimental search for Y(1915) is proposed by analyzing the omega f(0)(980) or omega pi pi invariant mass spectrum of the e(+)e(-) -> omega f(0)(980), omega pi pi, and J/psi -> eta omega f(0)(980) processes, which are accessible at Belle, BABAR, BESIII and forthcoming BelleII. Considering similarity between two families, the comparison of the mass spectra of omega and phi families can provide important information on the 1D state of phi family, phi(1910), which has a very broad resonance structure with mass around 1910 MeV regarded as the strangeonium partner of omega(1650). This also answers the question why the 1D state phi(1910) is still missing in experiment. This is supported by our former study on the properties of Y(2175), which explains Y(2175) as the 2D strangeonium because our theoretical total width is comparable with the Belle data.
