We employ an effective Lagrangian approach and use CERN LEP data to place severe bounds on universality violations of the couplings of (Formula presented) (Formula presented) and (Formula presented) to the Z boson. Our results justify the assumption of universality in these couplings that is usually made, such as, for example, in the analysis of solar neutrinos detected at SNO. © 2002 The American Physical Society.
