论文摘要
我们将领先的电荷对称性破坏贡献包括在手性有效野外理论中的超核相互作用中，直到近代到领先的顺序。使用4-lambda-He和4-Lambda-H的Lambda分离能的实验已知差异确定两个低能常数。这使人们可以根据数据首次预测Lambda-Neutron散射长度。讨论了各种不确定性来源。
We include the leading charge symmetry breaking contributions into the hyperon-nucleon interactions derived within chiral effective field theory up to next-to-leading order. Two low energy constants are determined using the experimentally known differences of Lambda separation energies of 4-Lambda-He and 4-Lambda-H. This allows one to predict the Lambda-neutron scattering lengths for the first time based on data. Various sources of uncertainty are discussed.
