Constraints on the $\Lambda$-neutron interaction from charge symmetry breaking in the ${}_{\mathbf{\Lambda }}^4\mathbf{He}$--${}_{\mathbf{\Lambda }}^4\mathbf{H}$ hypernuclei

Johann Haidenbauer, Ulf-G. Meißner, Andreas Nogga

We utilize the experimentally known difference of the $\Lambda$ separation energies of the mirror hypernuclei ${}_{\Lambda }^4\mathrm{He}$ and ${}_{\Lambda }^4\mathrm{H}$ to constrain the $\Lambda$-neutron interaction. W…
