9. Feasibility measurement of X-ray transitions in kaonic lead with HPGe detector at DAΦNE

Dr Ivica Friščić (Department of Physics, Faculty of Science, University of Zagreb)

The state-of-the-art value of the charged kaon mass is still less precise than the charged pion mass. Its value is important in the non-perturbative QCD, and it also important in a determination of systematic uncertainty of the D0-meson mass. Since there is a need and a possibility to improve the precision of this value, we will present ongoing analysis of feasibility measurement of X-rays...

10. High precision X-ray spectroscopy at the DAΦNE collider: with SIDDHARTA-2 experiment

High-precision X-ray spectroscopy of light kaonic atoms serves as a crucial method for exploring into low-energy QCD within the strangeness sector, allowing the determination of the antikaon-nucleon interaction at threshold without the need of extrapolation to zero energy The SIDDHARTA-2 collaboration is currently engaged in the complex task of measuring kaonic deuterium transitions to its...

16. Kaonic Atom Properties and Cascade Models: Exploring Strong Interactions through First-Principles Calculations

Simone Manti (INFN-LNF)

Kaonic atom experiments at SIDDHARTA2 provide a unique platform to explore the effects of strong interactions at low momenta. Specifically, during the de-excitation process of the highly excited kaonic atom, known as cascade, the emitted X-rays may be significantly influenced by the strong nuclear interaction between the nucleus and the kaon. Here, I present a detailed description of the...

18. The KAMEO proposal: investigating the strong kaon-nucleus interaction through the E2 nuclear resosnance effect in kaonic atoms

Luca De Paolis (INFN-LNF)

01/07/2024, 16:30

Kaonic atoms are atomic systems in which a negatively charged kaon is captured in the atomic shell, replacing an electron. The capture occurs at a highly excited atomic level, then the kaon starts an electromagnetic cascade to the innermost atomic levels, where the strong kaon-nucleus interaction becomes detectable with X-ray spectroscopy. Kaonic atoms allow the study of strong interaction in...

21. The role of dust in the star-formation and galaxy evolution, and its characteristic scaling relations

Dr Bogdan Adrian Pastrav (Institute of Space Science (RO))

01/07/2024, 17:00

Interstellar dust, a processor of stellar radiation, a gas coolant and a good interstellar medium (ISM) tracer, is formed out of elements mostly forged in stars. Its precise composition, grain size and distribution are essential for the galaxy attenuation curves, for the stellar or dust evolution models. Likewise, dust and star formation scaling relations are essential in studies of ISM...
