The DEAR experiment at LNF delivered the most precise data on kaonic hydrogen up to now and triggered new theoretical studies. DEAR and its follow-up experiment SIDDHARTA are using precision X-ray spectroscopy of kaonic hydrogen and kaonic deuterium atoms to measure the strong interaction induced shift and width of the ground state. From these observables the isospin-dependent antikaon-nucleon scattering lengths can be determined, thus contributing to the understanding of aspects of chiral symmetry breaking in the strangeness sector.
