Abstract: (arXiv)
Many extensions to the Standard Model imply the existence of new charged scalar Higgs bosons. We study the contribution of a general scalar or pseudoscalar coupling for the neutrino-electron scattering. We take a phenomenological approach in order to obtain model independent limits to the couplings that arise in this picture. We illustrate the reach of the constraints by studying the particular case of the type III two Higgs doublet model, where we have found new constraints to some elements of the Yukawa couplings mixing matrix (Yee1×101|Y_{ee}| \leq 1 \times 10^{-1} and Yeμ7×102|Y_{e\mu}| \leq 7\times10^{-2} at 90% CL).
