- Is there something sutble I'm missing about this reaction ? It seems kinamatically
- feasible, and there is (as David points out) a measured branching fraction for
- the corresponding electron channel. But this one isn't listed in either the
- allowed channels, or the CP violating "search" channels. So what gives ?
-
- But the answer to the original question is : For online reaction data,
- use SPIRES or the RALDurham database. Information on accessing these can
- be found in the front of the Particle Data Group's Review of Particle Propereties
- (Phys. Rev _D45_, part 2 (June 1992) if you are on this side of the planet).
