Web11 mrt. 2014 · Weyl spinors are in the "fundamental" rep of one of the su(2) s u ( 2) while they're in the trivial representation of the other. That is denoted by (1 2L,0R) ( 1 2 L, 0 R) or the other way around. The Dirac and Majorana representations happen to be a linear combination of the two Weyl representations (with maybe other conditions).

WebThere are many equivalent ways to write this representation as 4 4 matrices. The best-known ones are the Dirac, Weyl and Majorana representations. These are often presented in the form of 2 2 matrices whose elements are again 2 2 matrices. The latter are written using the Dirac matrices.

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. WebMajorana fermions are quite simple objects, simpler than Dirac fermions. But we are so much accustomed to Dirac particles that we try to understand Majorana particles …

WebMajorana found that this is indeed possible, but that it is nec- essary that the wave function transforms under unitary representations (UR) of the homogeneous Lorentz group.
