Measurement of the cross sections of $e^{+}{e}^{-}\to K_S^0{\bar{\mathrm{\Xi }}}^0\mathrm{\Lambda }\mathrm{/}{\mathrm{\Sigma }}^0+\text{c.c.}$ at center-of-mass energies between 3.510 and 4.951 GeV

Using $e^{+}{e}^{-}$ collision data samples collected with the BESIII detector at the BEPCII at center-of-mass energies between 3.510 and 4.951 GeV corresponding to an integrated luminosity of 44.55 fb${}^{-1}$, the Born cross sections of the processes $e^{+}{e}^{-}\to K_S^0{\bar{\mathrm{\Xi }}}^0\mathrm{\Lambda }\mathrm{/}{\mathrm{\Sigma }}^0+\text{c.c.}$ are measured with a partial-reconstruction strategy. The dressed cross sections for the channels $e^{+}{e}^{-}\to K_S^0{\bar{\mathrm{\Xi }}}^0\mathrm{\Lambda }\mathrm{/}{\mathrm{\Sigma }}^0+\text{c.c.}$ are fitted with a model consisting of a power-law function and a charmonium (-like) resonance, considering the candidates $\psi (3770)$, $\psi (4040)$, $\psi (4160)$, $Y(4230)$, $Y(4360)$, $\psi (4415)$, $Y(4500)$, $Y(4660)$, and $Y(4710)$. No significant resonance contribution is observed in any of the fits. The upper limits for the products of the electronic partial widths and branching fractions at the 90% confidence level are provided.
