Theoretical physicists investigated the mechanism for generating neutrino mass in the effective field theory. The paper by the Doctors of Physics and Mathematics Anatoly Borisov (Moscow State University) and Alexey Isaev (BLTP JINR) was issued in the Physics of Elementary Particles and Atomic Nuclei journal in 2024.

The seesaw mechanism for generating the mass of active light neutrinos (both Majorana and Dirac) is considered on the basis of effective field theory. Two appendices describe the properties of Weyl, Dirac and Majorana spinors and the relationships between them. The third appendix provides a simple proof of the theorem on the Takagi diagonalization of the mass matrix for Majorana fermions.
