This question relates to Griffiths: Introduction to Elementary Particles, p. 196
The process in question is a neutral pion decay into two photons. It is stated that because the secondary particles are massless, the amplitude for this process is:
M(p_2,p_3)
where p_2 and p_3 are the momentum...
Hello,
A question here about Classical Mechanics, Goldstein (Ed. 3)
On page 87 you have expression 3.33 which goes something like
\[
\frac{1}{r^2}\frac{d}{d\theta}\left(\frac{1}{mr^2}\frac{dr}{d\theta}\right)-\frac{l^2}{mr^3}=f(r)
\]
I appear to end up with
