On two-component equations for zero mass particles
Wilhelm I. Fushchych, A. L. Grishchenko
The paper presents a detailed theoretical-group analysis of three types of two-component equations of motion which describe the particle with zero mass and spin 1/2. There are stud…

On the CP-noninvariant equations for the particle with zero mass and spin s=1/2
Wilhelm I. Fushchych, A. L. Grishchenko
One of us quant-ph/0206077 (Nucl. Phys. B, 1970, 21, 321) has shown that for the particle with zero mass and spin s=1/2 there are three types of two-component equations (or one fou…
