The discussion centers on the classification of beta decay as a weak charge-current process. Participants clarify that any interaction involving the appearance or disappearance of charged particles qualifies as a charge-current process, specifically within the context of weak interactions. The conversation references a paper that outlines these processes, emphasizing that pair production and annihilation do not fall under this category. The consensus is that understanding these distinctions is crucial for accurately interpreting particle physics phenomena.
PREREQUISITESParticle physicists, students of quantum mechanics, and anyone interested in the nuances of weak interactions and beta decay processes.

Yes, I know what you mean. My point is that someone who is not a particle physicist might not.mfb said:... you know what I mean.
Weak processes only of course, and pair production/annihilation does not count.
