Abstract

We propose to test the validity of the multiplicative muon-number conservation law by comparing the quasielastic reactions

{\bar{ν}}_{μ} + e^{-} \to μ^{-} + {\bar{ν}}_{e}

and

ν_{μ} + e^{-} \to μ^{-} + ν_{e}

at ≳400 GeV. We note that the measured electron spectrum in muon decay places strong constraints on the effective Lagrangian for the

{\bar{ν}}_{μ}

-induced process.
