Neutrino interactions in liquid scintillators including active-sterile neutrino mixing

Neutrinos play an important role in core-collapse supernova events since they are a key piece to understanding the explosion mechanisms. The analysis of the neutrino fluxes can bring answers to neutrino’s related problems e.g., mass hierarchy, spectral splitting, sterile neutrinos, etc. In this work, we study the impact of neutrino oscillations and the possible existence of eV sterile neutrinos upon the supernova neutrino flux ([Formula: see text]). We have calculated the energy distribution of the neutrino flux from a supernova and the total number of events that would be detected in a liquid scintillator. We also present an analysis for the conversion probabilities as a function of the active-sterile neutrino mixing parameters. Finally, we have carried out a statistical analysis to extract values for the mixing parameters of the model.
