Leading contributed talk

The SIDDHARTA-2 experiment, conducted at the INFN-LNF DAΦNE collider, is currently engaged in a data collection campaign aimed at achieving the first-ever measurement of the strong-interaction-induced shift and width on the 1s level of kaonic deuterium. Exploiting the superior quality of the low-energy kaon beam provided by the DAΦNE collider in Frascati, Italy, and employing state-of-the-art...

It has been argued that the formation of a molecular-like quasi-bound state, $\Lambda(1405)$, arises from the strong attraction between $\overline{K}N$ with isospin I = 0 channel. Furthermore, its strong attraction suggests the existence of kaonic nuclei in a three-body system, $K^{-}pp$, as well as in more complex many-body systems.

Some calculations suggest existence of various types of...

It is important to investigate the in-medium quark condensates to understand the mechanism of the spontaneous breaking of chiral symmetry. The up and down quark condensates in nuclear medium are studied by pionic atoms and low energy pion nucleus scattering. It is found that the magnitude of the ud quark condensates may be reduced by 30% at the nuclear saturation density. This is known as...

126. Using light hypernuclei to constrain hypernuclear interactions

Contributed talk

Hypernuclei provide important information to constrain the hyperon-nucleon (YN) and three-baryon (YNN) interactions. In this contribution, we will discuss our recent results obtained using chiral YN [1,2] and chiral YNN interactions for light hypernuclei up to $A=8$.

We use the hypernuclei data to determine the charge-symmetry breaking (CSB) of YN interactions and for exploring the...

The possible existence of deeply-bound $\bar K$-nuclear bound states (kaonic nuclei) has been widely discussed as a consequence of the strongly attractive $\bar K N$ interaction in I = 0 channels. The investigation of kaonic nuclei can provide unique information about the $\bar K N$ interaction below the threshold, which is still not fully understood.

For the simplest kaonic nucleus, $\bar...
