Description

A new measurement of the neutron antineutrino spin asymmetry coefficient B in the beta decay of polarized neutrons is presented. The work was carried out on the polarized neutron vertical channel of the WWRM reactor. The value obtained implies that the mass of a hypothetical right-handed charged gauge boson in the left-right symmetric model of the weak interaction is greater than 281 GeV/c2 (90% CL). This is in agreement with restrictions from muon decay and direct searches for an additional vector boson W'. (K.A.)
