I Charge conjugation of Majorana pairs

  1. Mar 19, 2016 #1
    I was reading this article (http://arxiv.org/abs/1301.0021) about WIMP pair annihilation. At page six the author says that under charge conjugation a state of Majorana particles with orbital angular momentum ##L## and spin angular momentum ##S## take a phase ##(-1)^{L+S}##. I understand this for system of particle-antiparticle because under C the particle go into the antiparticle and vice versa so the spatial and spin wave functions give respectively a phase ##(-1)^L## and ##(-1)^{S+1}## on top of this the intrinsic parities give another ##(-1)## factor so we get the total phase factor ##(-1)^{L+S}##. But for Majorana two particles system under charge conjugation, being no distinction between particle and antiparticle, I expect than nothing happens under charge conjugation so that the system is CP even independently from the values of ##L## and ##S##. Where I'm wrong?
