Abstract:
We find an important constraint on the parameters of the general four-parameter left-right symmetric model. The constraint links the v-hadron sector of the model with the parity-violation sector. Using this constraint along with the available neutral-current data from neutrino-hadron and electron-deuteron scattering we find that, except for a narrow region amounting to essentially one point in the four-parameter space, the model is excluded. © 1980.
