Neutr<strong>in</strong>os <strong>in</strong> SN <strong>explosion</strong><br />
Neutr<strong>in</strong>os (<strong>of</strong> all flavours) are fundamental <strong>in</strong>gredients <strong>in</strong><br />
<strong>core</strong> <strong>collapse</strong> SN (Bethe (1990), Burrows (1990), Raffelt (2001));<br />
they . . .<br />
exchange energy with matter (heat<strong>in</strong>g and cool<strong>in</strong>g)<br />
release energy out <strong>of</strong> the system<br />
<strong>in</strong>fluence explosive nucleosynthesis<br />
give us important <strong>in</strong>formations about dense matter<br />
νe and ¯νe differ from νµ,τ and ¯νµ,τ<br />
orig<strong>in</strong> <strong>of</strong> the<br />
difference:<br />
me ≪ mµ ≪ mτ<br />
⇒ at the on-set <strong>of</strong> the <strong>collapse</strong>, Ye = 0<br />
while Yµ = Yτ ≈ 0<br />
