Query: Cross section measurement of $e^{+}e^{-} \to K_{S}^{0}K_{L}^{0}$ at
  $\sqrt{s}=2.00-3.08~{\rm GeV}$   The cross sections of the process $e^{+}e^{-} \to K_{S}^{0}K_{L}^{0}$ are
measured at fifteen center-of-mass energies $\sqrt{s}$ from $2.00$ to
$3.08~{\rm GeV}$ with the BESIII detector at the Beijing Electron Positron
Collider (BEPCII). The results are found to be consistent with those obtained
by BaBar. A resonant structure around $2.2~{\rm GeV}$ is observed, with a mass
and width of $2273.7 \pm 5.7 \pm 19.3~{\rm MeV}/c^2$ and $86 \pm 44 \pm 51~{\rm
MeV}$, respectively, where the first uncertainties are statistical and the
second ones are systematic. The product of its radiative width
($\Gamma_{e^+e^-}$) with its branching fraction to $K_{S}^{0}K_{L}^{0}$
($Br_{K_{S}^{0}K_{L}^{0}}$) is $0.9 \pm 0.6 \pm 0.7~{\rm eV}$.
