The viability of the 3+1 neutrino model in the supernova neutrino process

Understand

Adopting the 3+1 neutrino mixing parameters by the IceCube and shortbase line experiments, we investigate the sterile-active neutrino oscillation effects on the supernova neutrino process.

• For the sterile neutrino ($\nu_s$), we study two different luminosity models.
• First, we presume that the $\nu_s$ does not interact with other particles through the standard interactions apart from the oscillation with the active neutrinos.
• Second, we consider that $\nu_s$ can be directly produced by $\nu_e$ scattering with matter.
