Hypertriton appears more tightly bound than expected, sharpening the picture of nuclear forces

An international research team of the A1 Collaboration at the Mainz Microtron (MAMI) of Johannes Gutenberg University Mainz (JGU) has succeeded in determining the binding energy of the hypertriton with unprecedented precision. This experiment provides crucial new insights into the interaction between hyperons and nucleons—an aspect of the strong nuclear force that has so far remained insufficiently understood. The results show that the hypertriton is significantly more strongly bound than many earlier experiments suggested. The journal Physical Review Letters has recently published the study.
