Measurement of the e plus e⁺e^-  →ΛΛ‾ cross section from threshold to 3.00 GeV using events with initial-state radiation

Using initial-state radiation events from a total integrated luminosity of 11.957  fb−1 of 𝑒+⁢𝑒− collision data collected at center-of-mass energies between 3.773 and 4.258 GeV with the BESIII detector at BEPCII, the cross section for the process 𝑒+⁢𝑒− →Λ⁢¯Λ is measured in 16 Λ⁢¯Λ invariant mass intervals from the production threshold up to 3.00  GeV/𝑐2. The results are consistent with previous results from BABAR and BESIII, but with better precision and with narrower Λ⁢¯Λ invariant mass intervals than BABAR.
