      abstract     = {We utilize the experimentally known difference of the Λ
                      separation energies of the mirror hypernuclei 4ΛHe and 4ΛH
                      to constrain the Λ-neutron interaction. We include the
                      leading charge-symmetry breaking (CSB) interaction into our
                      hyperon-nucleon interaction derived within chiral effective
                      field theory at next-to-leading order. In particular, we
                      determine the strength of the two arising CSB contact terms
                      by a fit to the differences of the separation energies of
                      these hypernuclei in the 0+ and 1+ states, respectively. By
                      construction, the resulting interaction describes all low
                      energy hyperon-nucleon scattering data, the hypertriton and
                      the CSB in 4ΛHe-4ΛH accurately. This allows us to provide
                      first predictions for the Λn scattering lengths, based
                      solely on available hypernuclear data.},
