Abstract
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−→ \( {K}_S^0{K}_L^0 \)π0. The results allow the Born cross sections of the process e+e−→ \( {K}_S^0{K}_L^0 \)π0, 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−→ \( {K}_S^0{K}_L^0 \)π0 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 MY = (2164.7 ± 9.1 ± 3.1) MeV/c2 and its width as ΓY = (32.4 ± 21.0 ± 1.8) MeV.
