µ and τ neutrinos reactions
Reaction Current Important for . . .
ν + N → ν ′ + N ′ NC opacity
ν + A → ν ′ + A ′ NC opacity
ν + e ± → ν ′ + e ±′
NC energy exchange
e + + e − ↔ νx + ¯νx NC ν production
N + N ↔ N ′ + N ′ + νx + ¯νx NC ν production and energy exchange
N + N + ν → N ′ + N ′ + ν ′ NC energy exchange
νe + ¯νe ↔ νx + ¯νx NC ν production
νe + ν → ν ′ e + ν ′ NC secondary importance
¯νe + ν → ¯ν ′ e + ν ′ NC secondary importance
νx stands for both νµ and ντ
ν stands for both νx and ¯νx
