Enhanced Muonization by Active-Sterile Neutrino Mixing in Protoneutron Stars

Anupam Ray, Yong-Zhong Qian

We study ${\nu }_{\mu }$-${\nu }_s$ and ${\bar{\nu }}_{\mu }$-${\bar{\nu }}_s$ mixing in the protoneutron star (PNS) created in a core-collapse supernova (CCSN). We point out the importance of the feedback on the g…
