J-PARC E70实验是在J-PARC的强子实验装置上进行的一项测量12 <$Be超核丢失质量的实验。我们的目标是用一台新的磁谱仪S-2S在FWHM上达到2 MeV/c2的最佳丢失质量分辨率。超核的高分辨谱学对于理解未知的超核相互作用将起到重要作用。该实验将于2023年初开始。本文介绍了制备现状。
J-PARC E70 experiment measures the missing-mass of Ξ hypernuclei (12ΞBe) in Hadron Experimental Facility at J-PARC. We aim to reach the best missing-mass resolution of 2 MeV/c2in FWHM with a new magnetic spectrometer S-2S. The high-resolution spectroscopy of Ξ hypernuclei will play an important role to understand the unknown ΞN interaction. The experiment will start at the beginning of 2023. This article presents the preparation status.
