Constraints on the ΛΛ-neutron interaction from charge symmetry breaking in the Λ4He\mathbf{^4_Λ\rm \bf He}--Λ4H\mathbf{^4_Λ\rm \bf H} hypernuclei

By Johann Haidenbauer and others
We utilize the experimentally known difference of the Λ\Lambda separation energies of the mirror hypernuclei Λ4He{^4_\Lambda \rm He} and Λ4H{^4_\Lambda \rm H} to constrain the Λ\Lambda-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,...
