The lightest atomic systems, like kaonic hydrogen and kaonic deuterium, provide the isospin dependent kaon-nucleon scattering lengths by measuring the X-rays emitted during their de-excitation to the 1st level. The most precise kaonic hydrogen measurement to date was carried out at the DAFNE collider by the SIDDHARTA collaboration. The experimental information still missing in the field of the low-energy antikaon-nucleon interactions is the determination of the hadronic energy shift and width of kaonic deuterium, which will be measured by the SIDDHARTA-2 experiment. The SIDDHARTA-2 experiment will be installed on DAFNE in the second half of 2018.
