论文摘要
我们研究了不断扩大的保姆空间中Majorana费米子的动力学，我们为此目的构建了真空吸尘器在De Sitter Space中的Majorana Fermions构建。令人惊讶的是，Majorana繁殖器与Dirac Fermions相同。然后，我们使用此繁殖器并计算Majorana fermions的单环有效作用，并表明它与Dirac Fermions的不同之处在于1/2倍，这是主要粒子自由度的降低。最后，我们得出了混合典型的典型传播剂，用于混合典型的典型风味，它们适合研究量子环中的CP侵略效应。
We study the dynamics of Majorana fermions in an expanding de Sitter space and to that aim we construct the vacuum Feynman propagator for Majorana fermions in de Sitter space. Surprisingly, the Majorana propagator is identical to that of the Dirac fermions. We then use this propagator and calculate the one-loop effective action for Majorana fermions, and show that it differs from that of Dirac fermions by a factor of 1/2, which accounts for the reduced number of degrees of freedom of the Majorana particle. Finally, we derive the Majorana and Dirac propagators for mixing fermionic flavors, which are suitable for studying CP-violating effects in quantum loops.
