119. Updated experimental insight into the strong interaction between antikaons and nucleons.

Dr Oton Vazquez Doce (INFN e Laboratori Nazionali di Frascati (IT))

01/07/2022, 09:00

talk

The hadron physics sector with strangeness content faces a promising era with the arrival of new experimental data on the strong interaction between antikaons and nucleons (nucleii). The most recent and the upcoming measurements performed with traditional and new experimental approaches will be reviewed.

Measurements of correlations between particle pairs with low relative momentum via...

150. Kaonic atoms – status, results and plans

Johann Zmeskal (Stefan Meyer Institute for Subatomic Physics)

talk

Kaonic atoms are atomic systems where an electron is replaced by a negatively charged kaon, containing a strange quark, which interacts with the nucleus also by the strong interaction. As a result, the study of kaonic atoms offers the unique opportunity to perform experiments equivalent to scattering experiments, but at vanishing relative energy. These experiments will allow to study the...

116. Low-energy kaon-nucleon interaction studies by AMADEUS

Dr Kristian Piscicchia (CREF, LNF (INFN))

01/07/2022, 09:45

talk

The strong interaction theory in the low energy regime, is still missing fundamental experimental results in order to achieve a breakthrough in its understanding. Among these, the investigation of the low-energy kaon-nucleon/nuclei processes plays a key-role. The talk will give an outline of the results obtained by the AMADEUS experiment performed at the DAFNE Collider of LNF-INFN.

136. On K^- nuclear interaction, K^- nuclear quasibound states and K^- atoms

Dr Jaroslava Obertova (Nuclear Physics Insitute of CAS, Rez and Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University in Prague)

01/07/2022, 10:05

talk

The low-energy $K^-N$ interaction is currently described by chiral coupled-channel meson baryon interaction models. Above threshold, all the models agree between each other since their parameters are fitted to available low-energy $K^-N$ observables. However, in the subthreshold region, relevant for $K^-$ bound states, various models have different energy-dependence, which leads to a large...
