Kaonic atoms provide important observables for the study of the low-energy strong interactions with strangeness. Following SIDDHARTA’s kaonic hydrogen measurement, the SIDDHARTA-2 collaboration is performing the kaonic deuterium measurement, which will significantly enhance our understanding of kaon-nucleon interactions. Alongside this groundbreaking goal, the collaboration has provided other important measurements of kaonic atomt ransitions, which are significant not only for understanding low-energy strong interactions but also for studies in Quantum Electrodynamics. The experiment is also testing state-of-the-art X-ray detectors, paving the way for new technologies and future measurements of kaonic atoms with heavier nuclei.
