The study of the KbarN system at very low energies plays a key role for the understanding of the strong interaction between hadrons in the strangeness sector. At the DAFNE electron-positron collider of Laboratori Nazionali di Frascati we studied kaonic atoms with Z=1 and Z=2, taking advantage of the low-energy charged kaons from Phi-mesons decaying nearly at rest. The SIDDHARTA experiment used X-ray spectroscopy of the kaonic atoms to determine the transition yields and the strong interaction induced shift and width of the lowest experimentally accessible level (1s for H and D and 2p for He). Shift and width are connected to the real and imaginary part of the scattering length. To disentangle the isospin dependent scattering lengths of the antikaon-nucleon interaction, measurements of Kp and of Kd are needed. We report here on an exploratory deuterium measurement, from which a limit for the yield of the K-series transitions was derived: Y(K_tot)<0.0143 and Y(K_alpha)<0.0039 (CL 90%). Also, the upcoming SIDDHARTA-2 kaonic deuterium experiment is introduced.
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。
