论文摘要
物质 - 抗焦点的不对称性无法通过基本粒子物理的标准模型（SM）来解释。根据A. Sakharov的说法，需要$ \ MATHCAL {CP} $的其他来源违反现象才能理解物质 - 抗逆转录病毒的不对称性。亚原子基本粒子的电偶极矩（EDM）可能会提供额外的$ \ MATHCAL {CP} $违规，因为它们违反了$ \ Mathcal {t} $（和$ \ Mathcal {p} $）。存储环中的极化梁通过观察EDM对自旋运动的影响来测量带电颗粒的EDM。 Forschungszentrumjülich的冷却器同步器（舒适）提供极化的质子和Deuterons的势头为3.7 GEV/c，因此是绝地合作（JülichElectric Dipole Moments研究）的理想起点，以执行Deuteron EDM的第一个直接测量。本文档描述了Cozy的EDM活动的最新结果。
The matter-antimatter asymmetry cannot be explained by the Standard Model (SM) of elementary particle physics. According to A. Sakharov, additional sources of $\mathcal{CP}$-Violating phenomena are needed to understand the matter-antimatter asymmetry. Electric Dipole Moments (EDMs) of subatomic elementary particles may provide additional $\mathcal{CP}$ violation, since they violate $\mathcal{T}$ (and $\mathcal{P}$) symmetry. Polarized beams in storage rings offer the possibility to measure EDMs of charged particles by observing the influence of the EDM on the spin motion. The Cooler Synchrotron (COSY) at Forschungszentrum Jülich provides polarized protons and deuterons up to a momentum of 3.7 GeV/c and is therefore an ideal starting point for the JEDI - Collaboration (Jülich Electric Dipole moment Investigations) to perform the first direct measurement of the deuteron EDM. This document describes recent results of EDM activities at COSY.
