Abstract
Kaonic atoms, where a negatively charged kaon replaces an electron, provide a unique system for precision studies of bound-state and strong-field quantum electrodynamics (QED). The SIDDHARTA-2 experiment at the DAΦNE at INFN-LNF collider performs high-resolution X-ray spectroscopy of these systems using Silicon Drift Detectors. The recent measurement on kaonic neon enables stringent bound-state QED tests and a pathway towards a refined determination of the charged kaon mass, while preliminary kaonic fluorine data demonstrate the potential to probe strong-field QED effects. These results highlight the role of SIDDHARTA-2 in advancing high precision QED studies with hadronic atoms.
