Coherent nu-N scattering and the search for physics beyond the standard model

Abstract

We focus in future proposals to measure coherent neutrino-nuclei scattering and we show that such kind of experiments are very sensitive to nonstandard neutrino interactions with quarks. First in a model independent parametrization and then we focused in particular models such as leptoquarks and models with extra neutral gauge bosons and with R-parity breaking interactions. We show that in all these three different types of new physics it is possible to obtain competitive bounds to those of future collider experiments. For the particular case of leptoquarks we found that the expected sensitivity to the coupling and mass for most of the future experimental setups is quite better than the current constraints.
