Title: Recalibration of the binding energy of hypernuclei measured in emulsion experiments and its implications

Abstract

In this work, the $$ \Lambda $$ separation energy for $$ \Lambda $$ hypernuclei, denoted $$ B_\Lambda $$, measured in 1967, 1968, and 1973 are recalibrated using the current best estimates of the mass of particles and nuclei. The recalibrated $$ B_\Lambda $$ are systematically larger (except in the case of $$ ^6_\Lambda $$He) than the originally published values by about 100 keV. The effect of this level of recalibration is very important for light hypernuclei, especially for the hypertriton. The early $$ B_\Lambda $$ values measured in 1967, 1968, and 1973 are widely used in theoretical research, and the new results provide better constraints for the conclusions of such studies.
