Kaonic atoms studies with SIDDHARTA-2 at DAΦNE

The SIDDHARTA-2 experiment advances the study of kaonic atoms, focusing on kaonic deuterium and other kaonic atoms, such as neon, to explore low-energy Quantum Chromodynamics (QCD). Utilizing Silicon Drift Detectors and sophisticated veto systems, the experiment conducts high-precision X-ray spectroscopy to measure strong interaction-induced shifts and broadenings of atomic energy levels. This enables investigations of both electromagnetic and non-perturbative QCD effects, with high-n transitions facilitating precision tests of Quantum Electrodynamics (QED) and lower-level transitions providing insights into antikaon-nuclei strong interaction. Preliminary observations in kaonic neon highlight the potential for bridging theoretical predictions and experimental results.
