Neutral currents and Left‐Right Symmetric Models

We examine the Left‐Right Symmetric Model with Dirac neutrinos. The neutral currents are used to set a constraint on the mass of the additional neutral gauge boson; in particular, we find that a lower bound MZ2≥289 GeV can be set from neutrino‐electron scattering if we restrict ourselves to previously reported values for the L‐R mixing angle φ.
