High accuracy spectroscopy of 3- and 4-body Λ hypernuclei at Jefferson Lab

T. Gogami, Patrick Achenbach, T. Akiyama, D. Androić et autres

JLab E12-19-002 Experiment is planned to measure the Λ-binding energies of 3ΛH [Jπ = 1/2+ or 3/2+(T = 0)] and 4ΛH (1+) at JLab Hall C. The expected accuracy for the binding-energy measurement is |ΔBtotal Λ | ≃ 70 keV. The accurate …

Observation of Coulomb-Assisted Nuclear Bound State of Ξ−–N14 System

Shuhei H. Hayakawa, K. Agari, J. K. Ahn, Takaya Akaishi et autres

In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the …

Study on the baryon interaction by Ξ hypernuclear spectroscopy with the (K −, K +) reaction

T. Gogami, Shunsuke Kanatsuki, T. Nagae, J. K. Ahn et autres

We performed Ξ hypernuclear spectroscopy with the ( K − , K + ) reaction at J-PARC to investigate the Ξ N interaction (J-PARC E05). A new experiment (J-PARC E70) in which a better energy resolution could be achieved is now being …

Status of the J-PARC E07, Systematic Study of Double Strangeness Nuclei with the Hybrid Emulsion Method

Junya Yoshida, K. Agari, J. K. Ahn, Takaya Akaishi et autres

The current status of the J-PARC E07 experiment and two typical events, a _ΛΛBe hypernuclear event named “MINO” and \(_{\Xi }^{15}\text{C}\) hypernuclear event named “IBUKI”, are presented. J-PARC E07 is the most complex emulsion experiment so far to investigate double hypernuclei. The …

Status of J-PARC E07: Systematic study of double strangeness nuclei with hybrid emulsion method

Junya Yoshida, Keizo Agari, J. K. Ahn, Takaya Akaishi et autres

J-PARC E07 is the most complex emulsion experiment to date investigating double hypernuclei with a hybrid emulsion method. This experiment aims to detect 104 Ξ− stop events, ten times more events than the past experiments. Thus, an unequivocal identification of several new …

Observation of a Be double-Lambda hypernucleus in the J-PARC E07 experiment

H. Ekawa, K. Agari, J. K. Ahn, Takaya Akaishi et autres

A double-$\Lambda$ hypernucleus, ${}_{\Lambda\Lambda}\mathrm{Be}$, was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the $(K^{-},K^{+})$ reaction. This event was interpreted as a production and decay of $ {}_{\Lambda\Lambda}^{\;10}\mathrm{Be}$, ${}_{\Lambda\Lambda}^{\;11}\mathrm{Be}$, or ${}_{\Lambda\Lambda}^{\;12}\mathrm{Be}^{*}$ via $\Xi^{-}$ capture in ${}^{16}\mathrm{O}$. By assuming the …
