A Is beta decay a weak charge-current processes?

  1. Apr 11, 2017 #1
    Im try to understand this paper

    http://citeseerx.ist.psu.edu/vie...

    and see if I correctly understand which processes are charge-current processes, and which are charge neutral, as listed in Figure 1. Thanks

    Every process where charged particles appear or disappear is charged-current.

    ... you know what I mean.
    Weak processes only of course, and pair production/annihilation does not count.

    Yes, I know what you mean. My point is that someone who is not a particle physicist might not.
