Measurement of the e + e − → ${K}_{S}^{0}{K}_{L}^{0}$ π 0 cross sections from $\sqrt{s}$ = 2.000 to 3.080 GeV

Based on e + e − collision data collected at center-of-mass energies from 2.000 to 3.080 GeV by the BESIII detector at the BEPCII collider, a partial wave analysis is performed for the process e + e − → ${K}_{S}^{0}{K}_{L}^{0}$ π 0. The results allow the Born cross sections of the process e + e − → ${K}_{S}^{0}{K}_{L}^{0}$ π 0, as well as its subprocesses e + e − → K ∗(892)0 $\overline{K}$ 0 and ${K}_{2}^{\ast }$ (1430)0 $\overline{K}$ 0 to be measured. The Born cross sections for e + e − → ${K}_{S}^{0}{K}_{L}^{0}$ π 0 are consistent with previous measurements by BaBar, but with substantially improved precision. The Born cross section lineshape of the process e + e − K ∗(892)0 $\overline{K}$ 0 is consistent with a vector meson state around 2.2 GeV with a significance of 3.2σ. A Breit-Wigner fit determines its mass as M Y = (2164.7 ± 9.1 ± 3.1) MeV/c 2 and its width as Γ Y = (32.4 ± 21.0 ± 1.8) MeV.
