Abstract

• The binding energy of Xi-minus (Ξ- ) hyperon in nitrogen nucleus was estimated from single-Λ hypernucleus event which was detected in nuclear emulsion of J-ARC E07 experiment. The type of hypernucleus, its production and decay mode were obtained based on the conservation laws of energy and momentum. Moreover, the estimated value of the binding energy of Ξ- hyperon in nitrogen nucleus was 0.51 ± 0.17 MeV.
