LIGHTONS AND HELIXONS AS MASSLESS LIGHTLIKE PARTICLES IN GENERAL RELATIVITY |
Abstract _ |
A procedure of {\it lightlike limit} on Weyl's matrices level is applied to of massive Schwarzschild's, Kerr's and NUT's particles having an algebraic type {\bf D}. A velocity of moving particles tends towards the light velocity ($\,v \rightarrow 1$) along z axis and the total energy $E$ of is constant (i.e. a rest mass of the particle tends towards zero, $m_0 \rightarrow 0,\,E= const$) together with Kerr's angular momentum $L_z$ and with NUT's parameter $b$ which also tend to constants along z axis ($L_z = a\cdot m_0 \rightarrow J\cdot E$ and $b \rightarrow B=const$). As result of this procedure we have two sorts of massless lightlike particles: scalar particles ({\bf lightons}) and spinning particles with a helicity ({\bf helixons}).[1].A.M.Baranov //Vestnik of KrasSU (Phys.
