通过ALICE多奇异重子精密质量测量检验CPT对称性

Testing CPT symmetry via precision mass measurements of multi-strange baryons in ALICE

Romain Schotter

AI总结:

本文利用ALICE在LHC Run 2的pp碰撞数据,精密测量多奇异重子质量及粒子-反粒子质量差,显著提升精度,实现对CPT对称性的空前精确直接检验。

摘要:

在这些会议论文集中,报告了ALICE合作组在LHC Run 2期间收集的pp碰撞中,对$\Xi^-$、$\overline{\Xi}^+$、$\Omega^-$、$\overline{\Omega}^+$的质量以及粒子与反粒子之间质量差的测量结果。这些结果显著提高了相对于先前实验的精度,从而在多奇异重子领域允许对CPT对称性进行前所未有的精度水平的直接检验。

英文摘要:

In these proceedings, the measurements of the $Ξ^-$, $\overlineΞ^+$, $Ω^-$, $\overlineΩ^+$ masses and the mass differences between particle and anti-particle have been measured in pp collisions collected by the ALICE Collaboration during LHC Run 2. The results significantly improve the precision from previous experiments, thus allowing direct tests of CPT symmetry to an unprecedented level of precision in the multi-strange baryon sector.
