Study of Lambda/Sigma0 electroproduction

Abstract

Study of Lambda/Sigma0 electroproduction. Our international collaboration, consisting of researchers from Japan, Germany, the United States and others, has been experimentally studying Lambda hypernuclei. As a key experiment in our comprehensive series of projects, we conducted E12-17-003 experiment at the Thomas Jefferson National Accelerator Facility (JLab, USA) in 2018. In this experiment, we not only used the gas tritium target with the missing mass method to search for nnLambda states, but also used the gas hydrogen target to have important data.
