Knowledge of doubly strange hypernuclei and experimental prospect
Autor: Nakazawa Kazuma
Publikováno v: EPJ Web of Conferences, Vol 291, p 01015 (2024)
Experiments for doubly strange hypernuclei with nuclear emulsion have been performed at KEK and J-PARC for the past 30 years. From detected 47 events, the characteristics were understood for Λ-Λ interaction to be weakly attractive, linear mass numb

Autor: He, Yan, Drozd, Vasyl, Ekawa, Hiroyuki, Escrig, Samuel, Gao, Yiming, Kasagi, Ayumi, Liu, Enqiang, Muneem, Abdul, Nakagawa, Manami, Nakazawa, Kazuma, Rappold, Christophe, Saito, Nami, Saito, Takehiko R., Sugimoto, Shohei, Taki, Masato, Tanaka, Yoshiki K., Wang, He, Yanai, Ayari, Yoshida, Junya, Zhang, Hongfei
A novel method was developed to detect double-$\Lambda$ hypernuclear events in nuclear emulsions using machine learning techniques. The object detection model, the Mask R-CNN, was trained using images generated by Monte Carlo simulations, image proce

Hypertriton is the lightest hypernucleus and a benchmark in hypernuclear physics. However, it has recently been suggested that its lifetime and binding energy values may differ from the established values. To solve this puzzle, it is necessary to mea

Information and perspective for doubly-strange hypernuclei with nuclear emulsion detector
Autor: Nakazawa Kazuma
Publikováno v: EPJ Web of Conferences, Vol 271, p 11005 (2022)
The study on doubly-strange hypernuclei has been performed with nuclear emulsion detector at KEK-PS and J-PARC for 30 years. Detected 47 candidate events of doubly-strange hypernuclei show characteristics for the Λ-Λ and Ξ-N interactions. The Λ-

Autor: Aung Myo Thandar, Wint Thida, Myint Khin Swe, Nakazawa Kazuma
Publikováno v: EPJ Web of Conferences, Vol 206, p 09003 (2019)
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 th
