Since neutrino oscillation phenomenon was experimentally proved, several experiments have been built to measure the oscillation parameters and other topics related to them as the matter-antimatter asymmetry or the neutrino mass hierarchy. In this scenario, NuPRISM project was born to be an upgrade for the T2K experiment, and It involves a new concept of reconstructing neutrino energy: a neutrino spectrometer.
In the last decade, there were some anomalies in some neutrino oscillation experiments which cannot be explained with the known oscillation parameters, so a new state of neutrino was born to be a possible explanation. It seems that NuPRISM concept have a big potential in sterile searches, so we present some sensitivities studies within the NuPRISM project.
