本研究的目的是识别单Λ超核及其衰变产物,以支持获得有关超子核相互作用的更多信息。在进行单Λ超核分析之前,首先,我们通过使用钍系列的α衰变事件数据校准距离-能量关系来推导乳液的密度。这对于核乳状液中超核事件的质量重建非常重要。我们通过使用介子和非介子衰变模式的运动学重建来重建单Λ超核事件。从我们的分析结果中,我们可以唯一地确定单Λ超核是,衰变产物是4He、3He、质子和中子。
The purpose of this research is to identify a single-Λ hypernucleus and its decay products which support to get more information about hyperon-nucleon interaction. Before performing the analysis of a single-Λ hypernucleus, first, we have deduced the density of emulsion by calibrating the range-energy relation using alpha decay events data from thorium series. It is very important for the mass reconstruction of hypernucleus events in nuclear emulsion. And we have reconstructed a single-Λ hypernucleus event by using the kinematical reconstruction for mesonic and non-mesonic decay modes. From the result of our analysis, we can uniquely identify that single-Λ hypernucleus is and decay products are4He,3He, proton and neutron.
