Samalkhaiat,
Thank you for that reply. It is much clearer to me know how to obtain the scattering amplitude.
I was scratching my head trying to figure out the implication in the other direction.
The text was somewhat unclear in this regard.

Hi,
I am self-teaching Quantum Elctrodynamics, and have come across something which I do not understand. I would appreciate feedback from anyone on this specific issue from Atchison & Hey, "Guage Theories in Particle Physics" pg 238-239:
In calculating the u-channel electron-muon...
I have been teaching myself QFT and General Relativity. The mathematics of those fields is daunting, and I find that what I have come across is very difficult to master. Of course it will take work, but can someone recommend a good text for self-leaning differential geometry with application...
mpresic,
Thanks for your feedback. I am aware of the challenges facing me due to my age, but I am not daunted by them. I am curious to know, however, if you regret the experience (it sounds like you might).
Thank you for that feedback.
It is reassuring to know that others have pursued a PhD in physics when they
have been older. I hope that my experience and commitment will be viewed as
assets rather than hindrences. I know much more now than when I was younger
what I want and how to go...
I am 44 and want to get my PhD in Physics.
I am not really concerned about my ability or love of physics, but I am
somewhat concerned that there may be a bias against me in the admission
process because of my age. There is the fact that much of my formal
mathematical and physical...
