Kaonic Atoms
Oral Presentation
The Kbar-N system at rest makes a sensitive testing ground for the understanding of strong interaction at low energies. At the DAFNE electron-positron collider of Laboratori Nazionali di Frascati we study X-ray transitions of kaonic atoms, taking advantage of the low-energy kaons produced by Phi-mesons decaying nearly at rest. In the SIDDHARTA (Silicon Drift Detector for Hadronic Atom...

Kaonic Atoms
Oral Presentation
A brief summary of state-of-the-art analyses of kaonic atom data will
be presented, showing good consistency between the various experiments
of 30-40 years ago. Correlations between depths of real antikaon-nucleus
potentials and the corresponding radii provide a link between
phenomenology and 'microscopic' antikaon-nucleon interaction in the
nuclear medium. Further studies...

Kaonic Atoms
Oral Presentation
Properties and structure of the Lambda (1405) are interesting both in themselves and in the context of few-body and many-body nuclear states of anti-K mesons. One of the old problems is the place of Lambda (1405) in the quark models and related symmetries.
Another problem affecting the few body physics is related to the elastic anti-K nucleon scattering amplitude. The two approaches now...

Kaonic Atoms
Oral Presentation
An energy shift of the 2p level of kaonic 3He and 4He atoms is recently
studied in theory and experiment. A theory predicting deeply bound
kaonic nuclear states estimates a significant energy shift in kaonic
3He or 4He. The SIDDHARTA experiment measured the kaonic 3He and 4He
3d-2p X-ray transitions at the DAFNE e+e- collider. The strong interaction
shifts of the kaonic 3He and 4He 2p...

Strangeness in Matter
Oral Presentation
Formation of $K^-pp$ in high-energy $p+p$ collision is an elementary doorway step to excite kaonic nuclear clusters in nuclei. The $K^-pp$ system has a structure of $\Lambda^*$-$p$, where $\Lambda^*$ is $\Lambda(1405)$ embedded in the system. We have investigated theoretically how coupled-channel properties of $\Lambda(1405)$ change inside the quasi-bound system, $K^-pp$, by using "generalized...

Kaonic Atoms
Oral Presentation
The energy level displacement of the excited np state
of kaonic deuterium is calculated in terms of the P-wave scattering length
of K^-d scattering. We solve the Faddeev equations for the amplitude of
K^-d scattering in the fixed centre approximation and derive the complex
P-wave scattering length of K^-d scattering in terms of
the S-wave and P-wave scattering lengths of anti-KN
