Neutrino and Parity Violation in Weak Interaction

Abstract

It is shown that neutrino oscillation and Majorana type neutrino are not compatible with Special Theory of Relativity. Instead of the Majorana type neutrino, traditional neutrino(no rest mass) is considered with additional assumptions that right-handed neutrino and left-handed antineutrino exist in nature and naturally thus parity is conserved. Besides, neutrino itself is considered as longitudinal vacuum-string oscillations. To explain parity conservation, W+(W-) bosons are suggested as momentary interacting states between positron (electron) and virtual-positive(negative)-charge strings, respectively. With these postulations, an alternative explanation is also suggested for solar neutrino problem.
