- The W was most certainly not prepared as a plane wave. And I can assure
- you that the momentum and position resolution of a cloud chamber are nowhere
- near that required to test any uncertainty relations.
-
- Incidentally, you never see a track from a W, even in a modern detector,
- because it decays *way* too soon. I realize that we have suspended some
- rules of physics here for the sake of discussion, but I don't want anyone
- to be mislead that a W can really travel meters through a detector.
