121. Theory of few-body kaon-nuclear systems

online talk

The strong interaction between an antikaon and a nucleon is at the origin of various interesting phenomena in kaon-nuclear systems. In particular, the interaction in the isospin $I=0$ channel is sufficiently attractive to generate a quasi-bound state, the $\Lambda(1405)$ resonance, below the $\bar{K}N$ threshold. Based on this picture, it may be expected that the $\bar{K}N$ interaction also...

online poster

The existence of a quasi-bound state of antikaon and nucleus, kaonic nucleus, has been discussed ever since the $\bar{K}N$ interaction in $I=0$ channel was confirmed to be strong attractive.
The $\bar{K}NN$ quasi-bound state is the lightest kaonic nucleus which is considered to be $I=1/2$ and $J^\pi = 0^-$.
To search for the $I_{z}=+1/2~\bar{K}NN$ state we conducted the J-PARC E15 experiment...

34. Constraining the K̄N coupled channel dynamics using femtoscopic correlations with ALICE at the LHC

talk

The $\overline{\rm K}$p system is characterised by the presence of several coupled channels, systems like $\rm \overline{K}^0$n and $\rm \pi\Sigma$ with a similar mass and the same quantum numbers as the $\rm{K}^{-}$p state. The strengths of these couplings to the $\rm{K}^{-}$p system are of crucial importance for the understanding of the nature of the $\Lambda(1405)$ and of the attractive...

112. Future prospects of spectroscopy of Lambda hypernuclei at JLab and J-PARC HIHR

Prof. Satoshi N. Nakamura (The University of Tokyo)

talk

So far, the $(e,e' K^+)$ reaction spectroscopy is the only way to achieve sub-MeV energy resolution in Lambda hypernuclear reaction spectroscopy. As a part of the J-PARC hadron hall extension project, a new momentum dispersion matching beamline HIHR will be constructed. It will open the door to other reaction spectroscopy for precise measurement of Lambda hypernuclei with pion beams.
I will...

105. Hypernuclear gamma-ray spectroscopy: summary and future prospect

Mifuyu Ukai (KEK IPNS )

talk

$s$-shell to $sd$-shell hypernuclear gamma-ray spectroscopies were carried out at KEK-PS, BNL-AGS and J-PARC using  germanium detector arrays as the series of Hyperball project. These precise measurements of hypernuclear level structures gave various information on the $\Lambda$N interaction. In particular, the result from the gamma-ray spectroscopy of $^4_\Lambda$He ($1^+ \to 0^+$) M1...
