Results from the kaonic hydrogen X-ray measurement at DAFNE and outlook to future experiments
Abstract
The overline{K}N system at rest plays a key role for the understanding of strong interaction of hadrons with strangeness involved. The experiment SIDDHARTA used X-ray spectroscopy of kaonic atoms to measure the strong interaction induced shift and width of the ground state. It was the first experiment on kaonic He3 and deuterium ever, kaonic hydrogen was measured with improved precision resulting in ɛ_{1s} = -283 ± 36 (stat) ± 6 (syst) eV and Γ_{1s} = 541 ± 89 (stat) ± 22 (syst) eV. Additionally a scheme for an improved future experiment on kaonic deuterium is introduced in this contribution.
