Abstract

• A single- hypernucleus event which is detected in nuclear emulsion of J-PARC E07 experiment is analysed by applying relativistic kinematics. The ranges and position angles of charged particles tracks are calculated by using the position data supported by J-PARC E07 collaborators. The neutral particle emission at production point A and decay point B of single-Ʌ hypernucleus is checked by using the colinearity of two tracks and it is observed that, there is no neutral particle emission at point A but there is one or more neutral particles emission at point B. Charged particle track #4 is identified by its momentum and it is to be one of baryon families. The calculated results are compared with known experimental results. According to the analysis at point A, captured nucleus of Ξ- hyperon is identified as N 14 7 and the charged particle track #2 is identified as He 4 2 . At point B, single- hypernucleus track #1 is identified as Be 10  and charged particle track #3 and #4 are identified as Li 6 3 and H 1 1 . In addition to charged particles emission, neutral particles are contaminated at point B.
