Study of two quasidegenerate heavy sterile neutrinos in rare meson decays [PDF]

Physical Review D, 2021
In this work, we study the lepton-number-violating processes of $K^\pm$ and $D^\pm$ mesons. Two quasi-degenerate sterile neutrinos are assumed to induce such processes. Different with the case where only one sterile neutrino involves, here, the CP phases of the mixing parameters could give sizable contribution.

Two-dimensional models of core-collapse supernova explosions assisted by heavy sterile neutrinos [PDF]

Physical Review D
Core-collapse supernovae can be a copious source of sterile neutrinos, hypothetical particles that mix with active neutrinos. We develop two-dimensional stellar core-collapse models that incorporate the mixing between tau neutrinos and heavy sterile ...
