My question is how to compute the ratio of cross section (mediate by charge current) of neutrino/ anti neutrino of electron in a nuclei which is made of an equal number of proton's and neutrons The same question to neutral current.
I have to deliver soon my work.
I hope you can answer...
Can you explain better how to compute the (d_x,d_y,d_z) generators for euclidean space?
I don't understand really well how you can you do it just from the fact rot(W)=0 e div(W)=0

Homework Statement
My problem is to calculate to calculate killing vectors in 3-D euclidean space(flat space).
Homework Equations
The relevante equations are killing equation : d_a*V_b+d_b*V_a=0
The Attempt at a Solution
I found the solution in Ray D'Inverno and that is...
