Abstract

We propose a unique program of measurements of electric and magnetic dipole moments of charm, beauty and strange charged baryons at the LHC, based on the phenomenon of spin precession of channeled particles in bent crystals. Studies of crystal channeling and spin precession of positively- and negatively-charged particles are presented, along with feasibility studies and expected sensitivities for the proposed experiment using a layout based on the LHCb detector.

摘要

我们提出了一个在大型强子对撞机（LHC）上测量粲夸克、底夸克和奇异带电重子的电偶极矩和磁偶极矩的独特方案，该方案基于在弯曲晶体中沟道化粒子的自旋进动现象。文中介绍了对带正电和带负电粒子的晶体沟道化及自旋进动的研究，以及使用基于LHCb探测器的布局对所提议实验进行的可行性研究和预期灵敏度分析。
