On the CP-noninvariant equations for the particle with zero mass and spin s=1/2
Abstract
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 four-component equation with three different subsidiary conditions) which differ from one another by P, T and C properties. One of these equations is the two-component Weyl equation. In this note we give two other relativistic invariant equations.
