Description
We are going to perform missing mass spectroscopy of various $\Lambda$ hypernuclei using the $(e,e'K^{+})$ reaction at the Thomas Jefferson National Accelerator Facility (JLab). This experimental campaign contains the first measurement of medium-mass hyperisotopes of $^{40}_{\Lambda}\mathrm{K}$ and $^{48}_{\Lambda}\mathrm{K}$ using isotopically enriched calcium target [JLab E12-15-008]. The intense electron beam and high resolution spectrometers achieve will much better energy resolution, at a sub-MeV level, than the existing hadronic experiments. Precise and accurate measurement of the medium-mass hyperisotopes will enable us to investigate the ${\Lambda}N$ interaction in nuclei including the ${\Lambda}NN$ three-body force which plays a key role for the stiffness of neutron stars. I will talk about the experimental prospects and the expected results of these measurements based on detailed simulation and study.
