Cpt, Cp, And C Transformations Of Fermions, And Their Consequences, In Theories With B − L Violation, Susan Gardner, Xinshuai Yan

Physics and Astronomy Faculty Publications

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 …
