费米子的CPT、CP和C变换及其在B-L破坏理论中的结果

CPT, CP, and C transformations of fermions, and their consequences, in theories with B-L violation

Susan Gardner, Xinshuai Yan

摘要:

本文研究了在B-L破坏存在下,费米子在CPT、CP和C离散对称下的变换性质。因此,我们推广了已知的马约拉纳中微子的性质的分析,通过无中微子双β衰变探测,包括狄拉克费米子的情况下,B-L破坏,这可以通过中子-反中子振荡探测。我们发现,由此产生的CPT阶段的影响与外部字段和源的中子-反中子振荡的相互作用,并考虑在马约拉纳动力学的中微子和中子的自共轭同位旋I=0和I=1/2字段的理论的背景下的差异。

英文摘要:

We consider the transformation properties of fermions under the discrete symmetries CPT, CP, and C in the presence of B-L violation. We thus generalize the analysis of the known properties of Majorana neutrinos, probed via neutrinoless double beta decay, to include the case of Dirac fermions with B-L violation, which can be probed via neutron-antineutron oscillations. We show that the resulting CPT phase has implications for the interplay of neutron-antineutron oscillations with external fields and sources and consider the differences in the Majorana dynamics of neutrinos and neutrons in the context of theories with self-conjugate isospin I=0 and I=1/2 fields.
