Standard Model precision tests with high intensity and low energy neutrino beams

Abstract
The Standard Model theory has been deeply tested in tha last years and its parameters have been determined with very high accuracy, mainly at high energy accelerators. However, it could be important to improve the knowledge of these parameters also in the region of medium and low energies. From this point of view a very important role could be played by neutrino physics, as it happened already in the past. Despite the many important results obtained during the last years in neutrino physics, a lot of important questions are still open in this field. In the near future we will have at our disposal a series of experiments, using artificial neutrino beams from reactors and accelerators, which will provide us with beams of very high intensities (never reached before) and relatively low energies. These experiments could be useful, not only to improve our knowledge of neutrino properties, but also to perform Standard Model tests at low energies. We have studied in detail the feasibility of this research project, extending to beta beams and mainly to superbeams the analysis already available for neutrino factories. We focused, in particular, our attention on the possibility of extracting from these experiments the value of Weinberg angle at low energy, separating it from our partial ignorance of the nucleon form factors. In this talk I briefly review some recent results, the present status and future perspectives of neutrino physics and then I discuss the main ingredients and results of our analysis.
