Abstract: We show how neutrino data can be used in order to constrain the freeparameters of possible extensions to the standard model of elementary particlesSM. For definiteness, we focus in the recently proposed unparticle scenario.We show that neutrino data, in particular the MUNU experiment, can set strongerbounds than previous reported limits in the scale dimension parameter forcertain region d > 1.5. We compute the sensitivity of future neutrinoexperiments to unparticle physics such as future neutrino-electron scatteringdetectors, coherent neutrino-nuclei scattering as well as the ILC . Inparticular, we show that the measurement of coherent reactor neutrinoscattering off nuclei provide a good sensitivity to the couplings of unparticleinteraction with neutrinos and quarks.Finally our results are compared with thecurrent astrophysical limits.
