Charge symmetry breaking in light hypernuclei
Collaboration

Abstract content
At the Mainz Microtron MAMI the high-resolution spectroscopy of decay-pions in strangeness electro-production is used to extract the $\Lambda$ hyperon ground state binding energy in $^4_\Lambda$H. This binding energy is used together with the $^4_\Lambda$He ground state binding energy from nuclear emulsion experiments and with energy levels of the $1^+$ excited state for both hypernuclei from $\gamma$-ray spectroscopy to address the charge symmetry in the strong interaction. The full understanding of the large and spin-dependent breaking of this symmetry in the $A = 4$ hypernuclei still remains one of the open issues of hypernuclear physics.
