Hi, I'm in the process of revision for upcoming exams, one likely question will give a number of decays (~5) and ask if they are possible.
I understand baryon number, lepton number (and parity, isospin, and strangeness) must be conserved, but for example for the following:
K+ -> neutral pion + positron + electron neutrino
K+ -> neutral pion + positive pion
p -> neutral pion + positron
What's the best way to determine if they are possible? Also it will ask about the force responsible for the decay, how do i determine this?
Thanks in advance for any guidance!
