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.
