Abstract:

The lambda-separation-energy-difference (ΔB_Λ) between _Λ⁴He and _Λ⁴H caused by the OPE-type charge-symmetry-breaking (CSB) component in the ΛN interaction is calculated. ΛN potentials including tensor forces are employed. It is shown that the contribution from the coupling of the CSB tensor component and the ΛN tensor force is essential for ΔB_Λ and that the experimental ΔB_Λ demands ΛN tensor force of negative sign.
