In the past two decades, a plethora of hadronic states beyond the conventional quark model
of qq ̄ mesons and qqq baryons have been observed experimentally, which motivated …

The Λ (1405) baryon resonance plays an outstanding role in various aspects in hadron and
nuclear physics. It has been considered that the Λ (1405) resonance is generated by the …

The effective K¯ N interaction based on chiral SU (3) coupled-channel dynamics is derived
and its extrapolation below the K¯ N threshold is studied in detail. Starting from the coupled …

The ppK-system, as a prototype for possible quasibound K¯ nuclei, is investigated using a
variational approach. Several versions of energy-dependent effective K¯ N interactions …

This review covers the modern era of experimental kaonic atom studies, encompassing 20
years of activity, defined by breakthroughs in technological developments which allowed …

Since the shutdown of several old proton synchrotrons, which played a fundamental role in
the second generation experiments in hypernuclear physics performed in Europe, USA and …

We observed a distinct peak in the Λp invariant mass spectrum of He 3 (K−, Λ p) n, well
below m K+ 2 mp, ie, the mass threshold of the K− to be bound to two protons. By selecting a …

A search for the K− pp bound state (the lightest kaonic nucleus) has been performed using
the γ d→ K+ π− X reaction at E γ= 1.5–2.4 GeV at LEPS/SPring-8. The differential cross …

AK¯ K¯ N system with I= 1/2 and JP= 1/2+ is investigated with nonrelativistic three-body
calculations by using effective K¯ N and K¯ K¯ interactions. The present investigation …
