摘要:

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。

英文摘要:

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.
