While researching baryon asymmetry, I came across this article discussing problems with the Standard Model, where it is noted that:
The Standard Model did not and cannot predict the masses of the fundamental particles that make up all of the luminous matter that we can observe. QCD still cannot retrodict the mass of the proton without considerable fudging, and even then it is only good to within 5%. As for retrodicting the mass of the electron, the SM cannot even make an attempt.
I'm not entirely sure I understand what such a retrodiction would look like.
Can someone point me to an example of a formula (including Standard Model) that successfully, accurately retrodicts the mass of a particle and how this is accurately calculated?
EDIT: Sorry, I was really only curious about what retrodiction of a particle's mass looked like and ended up with a response about prediction because of an edit that was not by me. Should I re-ask in a more specific fashion?
