Observation of Spin-Dependent Charge Symmetry Breaking in ΛN Interaction: Gamma-Ray Spectroscopy of _{Λ} ^{4} He

Author(s): T. O. Yamamoto et al. (J-PARC E13 Collaboration)

The energy spacing of the spin-doublet states in the ${}_{\mathrm{\Lambda }}^4$He hypernucleus indicate a large spin dependent charge symmetry breaking in the $\mathrm{\Lambda }N$ interaction.
