Dark matter sterile neutrinos in stellar collapse: Alteration of energy/lepton number transport, and a mechanism for supernova explosion enhancement

Abstract: We investigate matter-enhanced Mikheyev-Smirnov-Wolfenstein (MSW) active-sterile neutrino conversion in the νe ⇋ νs channel in the collapse of the iron core of a pre-supernova star. For values of sterile neutrino rest mass ms and vacuum mixing angle θ (specifically, 0.5 keV < ms < 10 keV and sin 2 2θ > 5 × 10 −12 ) which include those required for viable sterile neutrino dark matter, our one-zone in-fall phase collapse calculations show a significant reduction in core lepton fraction. This would result in a sm… Show more

“…In this section we briefly summarize our previous work [32] on the effects of active-sterile neutrino flavor conversion on the in-fall phase of a core collapse supernova. The key result of this earlier work was the discovery that electron neutrino conversion into a sterile neutrino species ν e → ν s could feed back on electron capture (e − + p → n + ν e ) during collapse and alter the potential governing flavor transformation so as to produce a double Mikeyev-Smirnov-Wolfenstein (MSW) resonance [33,34].…”

“…The underlying particle model, called the νMSM, is described in detail in a number of papers (Asaka et al , 2007Shaposhnikov & Tkachev 2006;Shaposhnikov 2008;Gorbunov & Shaposhnikov 2007;Laine & Shaposhnikov 2008;Canetti et al 2013a), and recent reviews (Boyarsky et al 2009b;Kusenko 2009;Drewes 2013). Additionally, the sterile neutrino may have interesting effects on a range of astrophysical objects, for example as an explanation for pulsar kick velocities, facilitating core collapse supernova explosions, affecting early star formation, reionization and structure formation, or assisting inflation (Kusenko & Segrè 1997;Kusenko et al 2008;Hansen & Haiman 2004;Fryer & Kusenko 2006;Hidaka & Fuller 2006;Biermann & Kusenko 2006;Mapelli et al 2006;Shaposhnikov & Tkachev 2006;Bezrukov & Shaposhnikov 2008;Petraki & Kusenko 2008;Petraki 2008;Boyanovsky 2008;Gorbunov et al 2008). The lightest of the three sterile neutrinos provides an attractive dark matter candidate.…”
