论文摘要

Kaonic原子是探索低能能以陌生部门探索量子染色体动力学的独特工具，其含义达到了中子恒星和暗物质。精确的X射线光谱可以通过原子过渡到基本水平完全解锁依赖性的依赖依赖的依赖性的依赖性抗Kaon-Nucleon散射长度。尽管在Infn-Lnf Da $φ$ NE对撞机上的Siddharta实验成功地测量了Kaonic氢，但其后继Siddharta-2现在开始使用其数据吸收活动，目的是通过测量Kaonic Deuterium的测量来完全消除Isoscalar和Isovector散射长度。提出了Siddaharta-2实验预备运行的第一个实验结果的概述。

Kaonic atoms are a unique tool to explore quantum chromodynamics in the strangeness sector at low energy, with implications reaching neutron stars and dark matter. Precision X-ray spectroscopy can fully unlock the at-threshold isospin dependent antikaon-nucleon scattering lengths, via the atomic transitions to the fundamental level. While the SIDDHARTA experiment at the INFN-LNF DA$Φ$NE collider successfully measured kaonic hydrogen, its successor SIDDHARTA-2 is starting now its data taking campaign aiming to finally fully disentangle the isoscalar and isovector scattering lengths via the measurement of kaonic deuterium. An overview of the first experimental results from a preparatory run for the SIDDAHARTA-2 experiment is presented.
