Is it possible for an electron to collide with another electron?

Tricky question. It is not difficult to answer. Electrons collide all of the time. One emits a photon or a vector boson, and the other absorbs it, transferring momentum. While the photon-mediated collision has a long range, the Z-mediated collision has a much shorter range. It looks like the electrons “hit eachother”, but it doesn’t. It isn’t possible.
