Majorana Mass Term of Majorana Spinors

Abstract

We have proven that, under the standard charge conjugation approach, the Majorana mass term in QFT must vanish. We have derived formulas for the Majorana spinor field operator without any assumptions about the second quantization procedure. The fact that the Majorana mass term vanishes not only in the c-theory, which was known, but also in the q-theory (the theory of second quantization), requires a revision of ideas about the generation of neutrino mass using the seesaw mechanism.
