Majorana representation of groups

Webthough the Majorana representation does enlarge the spin’s Hilbert space, it is believed that it does not suffer from unphysical states. However, the Majorana representation has not been used very often, which points to a lack of trust in this respect. Therefore, we think that there is a need for clarification. Second, if applied in a ... WebThe classification of Majorana representations restricted to the closed shapes was anticipated for a long time. In the present article the classification is achieved for shapes …

WebWe first derive without recourse to the Dirac equation the two-component Majorana equation with a mass term by a direct linearization of the relativistic dispersion relation of a massive particle. Thereby, we make only use of the complex conjugation operator and the Pauli spin matrices, corresponding to the irreducible representation of the Lorentz group.

WebAccordingly a Majorana spinor or Majorana fermion is a spinor / fermion corresponding to such a representation under Wigner classification. None of the particles in the standard model of particle physics except possibly the neutrinos are Majorana fermions (for neutrinos this remains open). WebSince SO(2) is an Abelian group, this representation must be reducible. We can decompose this representation into its irreducible components by using either the …
