Measurements of Normalized Differential Cross Sections of Inclusive & π0 and K0S 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 K0S production as a function of hadron momentum, normalized by the total cross section of the e+e- & RARR; hadrons process, are measured at six center-of-mass energies from 2.2324 to 3.6710 GeV. Our results, which cover a relative hadron energy range from 0.1 to 0.9, significantly deviate from several theoretical calculations based on existing fragmentation functions.
