JLab Hypernuclear Collaboration Meeting 2025

Hyeprnuclear spectroscopy at Jefferson Lab has a unique role for investigating the baryon interactions with the strangeness degrees of freedom. We are planning to perform experiments with high reoslution spectrometers, HES and HKS, which are dedicated to hypernuclear missing-mass spectrosocpy. The experiments will measure hypernuclei with wide nuclear masses ranging from A = 3 to 208 for systematic studies to pin down various physics topics such as charge symmetry breaking (CSB), multi-body Lambda-NN interaction, hypertriton puzzle, hyperon puzzle in neutron stars, search for triaxially deformation states etc.

In this collaboration meeting, significance and impact of the hypernuclear project at JLab will be shared and discussed. In addition, some preparation updates, aiming at the performance of experiments from 2027, will be shown.
