Can the new states around 2.2 GeV be identified as the ω(3D)?

Abstract

Recently, the BESIII Collaboration reported that there exist two explicit enhancement structures near 2.25[Formula: see text]GeV, one has the mass of [Formula: see text][Formula: see text]MeV and the width of [Formula: see text][Formula: see text]MeV and another structure has the mass of [Formula: see text][Formula: see text]MeV and the width of [Formula: see text][Formula: see text]MeV when analyzing the cross section of subprocesses. Earlier, the BESIII Collaboration reported the existence of the [Formula: see text], with a mass of [Formula: see text][Formula: see text]MeV and width of [Formula: see text][Formula: see text]MeV. Based on these experimental results, we carried out a study. We present the comparison of the mass spectrum between theoretical and experimental masses and examine the two-body strong decays of these states within two different approaches to the [Formula: see text] model. We find that the newly discovered states are most likely to be an [Formula: see text] state. This discovery could be useful in establishing entire [Formula: see text] mesons.
