论文摘要
短寿命颗粒的电磁偶极矩对粒子物理的标准模型内外的物理敏感，但迄今为止尚未在实验上访问。为了进行此类测量，已经提出要利用LHC弯曲晶体中通道颗粒的自旋进动。据报道，据报道，据报道，据报道，可以进行首次测量的进度。特别是，讨论了硅和锗弯曲晶体原型的设计和表征，实验设置的优化以及高级分析技术。灵敏度研究表明，可以在两年的数据中进行第一次测量$λ_c^+$和$ξ_c^+$ baryon偶极矩，并在两年的数据中使用LHCB检测器上游的实验设置。
Electromagnetic dipole moments of short-lived particles are sensitive to physics within and beyond the Standard Model of particle physics but have not been accessible experimentally to date. To perform such measurements it has been proposed to exploit the spin precession of channeled particles in bent crystals at the LHC. Progress that enables the first measurement of charm baryon dipole moments is reported. In particular, the design and characterization on beam of silicon and germanium bent crystal prototypes, the optimization of the experimental setup, and advanced analysis techniques are discussed. Sensitivity studies show that first measurements of $Λ_c^+$ and $Ξ_c^+$ baryon dipole moments can be performed in two years of data taking with an experimental setup positioned upstream of the LHCb detector.
