Abstract
In order to include massive neutrino theoretically,a new concept of the weak charge of particles,fundamental fermions,intermediate bosons and hadrons,is introduced.A new conservation law of the weak charge is first reported.Possible experiments are suggested which might test whether the weak charge is present.According to the chirality of the weak charge the origin of parity nonconservation in the weak interactions is reasonably explained.According to the symmetry of the weak charge,an extension of the standard model is proposed.In this scenario,all the three generations of neutrinos are massive Dirac particles,but the weak charges of the right-handed neutrinos and the left-handed antineutrinos are both zero,and so they do not take part in the weak interactions and are called the dark particles.关键词
