Measurement of the $e^{+}{e}^{-}\to \Lambda \bar{\Lambda }$ cross section from threshold to 3.00 GeV using events with initial-state radiation

BESIII Collaboration, M. Ablikim, M. N. Achasov +600

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…
