Measurements of Differential Cross Sections of Inclusive ${\pi }^0$ and $K_S^0$ Production in $e^{+}{e}^{-}$ Annihilation at Energies from 2.2324 to 3.6710 GeV

Based on electron positron collision data collected with the BESIII detector operating at the BEPCII storage rings, the differential cross sections of inclusive ${\pi }^0$ and $K_S^0$ production as a function of hadron momentum, normalized by the total cross section of the $e^{+}{e}^{-}\to$ hadrons process, are measured at six center-of-mass energies from 2.2324 to 3.6710 GeV. Our results with a relative hadron energy coverage from 0.1 to 0.9 significantly deviate from several theoretical calculations based on existing fragmentation functions, especially at lower energies.
