CONTRIBUTION OF NEUTRINO (ANTINEUTRINO) MASS IN POLARIZATIONS AND ASYMMETRIES OF PARTICLES IN β-DECAY PROCESSES

Abstract

Purpose. The possibility of determining the neutrino mass (antineutrino) is evaluated by measuring relative characteristics instead of the traditional measurement of the electron energy spectrum (positrons) at its end. Methodology and Approach. The idea of the method is to minimize the influence of poorly studied structures of nuclei and nucleons on relative quantities measured in experiments, such as polarizations and asymmetries of particles. Results. The possibility of conducting new laboratory experiments to determine the neutrino mass (antineutrino) by measuring asymmetries and polarizations of particles instead of the traditional measurement of the energy spectrum of electrons (positrons) at its end is theoretically shown. Theoretical and Practical implications. The results of the study will help better understand the neutrino physics and the theory of electroweak interactions.
