    Graduate Neutral Current and charged current(weak interactions)

    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...

    Graduate Killing vectors on a 3D Euclidean space

    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 Regards

    Calculate Killing Vectors in 3-D Euclidean Space

    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...
