Actually, now I am convinced that I am right and my tutor made a mistake.
In order for this to be Lorentz invariant, the threshold energy s = |Pphoton,i + Pelectron,i|² = |Pphoton,f + Pelectron,f|²
So we MUST square each side first, otherwise it is not invariant.
Can anyone...
Thanks CompuChip.
Yes, that makes sense mathematically. It's the physics that I still am not getting. What is the reason for squaring both sides? Does that give us the square of the rest mass?
Homework Statement
Hey all, this is my first post to the forum, but I've been reading for years. Anyways, I was reviewing a solution to a Compton Scattering derivation we learned in class, and am still trying to make sense out of it.
