Neutr<strong>in</strong>o-matter <strong>in</strong>teraction<br />
Neutr<strong>in</strong>os <strong>in</strong>teract significantly by charged (CC) or neutral<br />
(NC) current reactions with matter at high ρ and T<br />
Major consequences:<br />
opacity a<br />
κ ∼ 5 × 10−20 2 Eν 2 −1<br />
MeV cm g ⇒ 0 τν 103 for Eν ≈ 20MeV<br />
a κ → opacity, λν → ν mean free path, τν → ν optical depth<br />
