The interaction of antikaons with nucleons and nuclei in the low-energy regime represents an active research field in hadron physics with still many important open questions. The investigation of light kaonic atoms, in which one electron is replaced by a negatively charged kaon, is a unique tool to provide precise information on this interaction; the energy shift and the broadening of the low-lying states of such atoms, induced by the kaon-nucleus hadronic interaction, can be determined with high precision from the atomic X-ray spectroscopy, and this experimental method provides unique information to understand the low energy kaon-nucleus interaction at the production threshold. The lightest atomic systems, like the kaonic hydrogen and the kaonic deuterium deliver, in a model-independent way, the isospin-dependent kaon-nucleon scattering lengths. The most precise kaonic hydrogen measurement to-date, together with an exploratory measurement of kaonic deuterium, were carried out in 2009 by the SIDDHARTA collaboration at the DAΦNE electron-positron collider of LNF-INFN, combining the excellent quality kaon beam delivered by the collider with new experimental techniques, as fast and very precise X-ray detectors, like the Silicon Drift Detectors. The SIDDHARTA results triggered new theoretical work, which achieved major progress in the understanding of the low-energy strong interaction with strangeness reflected by the antikaon-nucleon scattering lengths calculated with the antikaon-proton amplitudes constrained by the SIDDHARTA data. The most important open question is the experimental determination of the hadronic energy shift and width of kaonic deuterium; presently, a major upgrade of the setup, SIDDHARTA-2, is being realized to reach this goal. In this paper, the results obtained in 2009 and the proposed SIDDHARTA-2 upgrades are presented.
Kaonic Atoms at the DA$Φ$NE Collider with the SIDDHARTA-2 Experiment
Kaonic原子是探索低能奇异区量子色动力学的独特工具，其影响涉及中子星和暗物质。精确的X射线光谱学可以通过原子到基本能级的跃迁，完全解开与阈值同位旋相关的反K介子-核子散射长度。虽然在INFN-LNF DA $Φ$ NE对撞机上进行的SIDDHARTA实验成功地测量了K介子氢，但其后继者SIDDHARTA-2现在正在开始其数据采集活动，旨在通过测量K介子氘最终完全解开等熵和等矢量散射长度。概述了SIDDAHARTA-2实验的准备运行的第一个实验结果。
