Abstract

• A single- hypernucleus event is kinematically analyzed in this research paper. The analyzed event was observed in KEK-PS E373 experiment. In this research work, a single- hypernucleus was produced by the direct process of hypernuclei studies. From the experimental studies, ranges of tracks #1, #2, #3, #4 and #5 are 40.10  0.30 m, 414.93  0.48 m, 9.11  0.03 m, 9.47  0.15 m and 10800.90  0.00 m. By using these ranges, Q-value, total kinetic energy, reconstructed mass and mass difference are calculated. We checked conservation laws so that 167 decay modes are obtained. All negative Q-values are neglected as the first step of our analysis. Furthermore, comparison of Q-value and visible energy released are performed and then mass of single- hypernucleus is calculated. Finally, we have obtained 13 decay modes. According to our calculated results, only two decay modes, Li → p+ He+ p + π 4 - 2 6 Λ and Li → p + p+ He + π 4 - 2 6 Λ are possible with the same single-strangeness hypernucleus. Due to the percentage of mass difference, Li → p + p+ He + π 4 - 2 6 Λ is more acceptable between the most possible two decay modes. Qvalue and total kinetic energy or visible energy released of Li 6 Λ are 35.27  0.00 MeV and 35.25  0.06 MeV. The mass difference of the single- hypernucleus is 0.019 MeV/c2 . According to our calculating results, a single- hypernucleus was identified as a Li 6 Λ hypernucleus.
