Abstract

We consider the effect of complex Higgs triplets on purely leptonic processes and survey the experimental constraints on the mass and couplings of their single and double charge members. Present day experiments tolerate values of the Yukawa couplings of these scalars at the level of the standard electroweak gauge couplings. We show that the proposed measurement of the ratio RLCD = σ(νμe)/[σ(ν̄μe) + σ(νee)] would allow to explore a large region of the parameter space inaccessible to the usual ratio R = σ(νμe)/σ(ν̄μe).
