- There is more call for skepticism, perhaps, than most people would
- think. We have been through this so many times that I have almost zero
- expectation that this will amount to anything. Six months ago it was
- an anomalous rate of e+ + e- -> Z0 -> four leptons that had people excited.
- Today it's two leptons and two photons. Tommorrow it will be three photons
- and a grapefruit. In the end, in my experience, 9 out of 10 (if not more!)
- such claims quietly fade away.
-
- What we have here is some graduate student who sifted through tens of
- gigabytes of data, 100's of thousands of (presumed) Z0 decays to find
- 7 events which are thought to belong to a certain class. There are
- dozens of reasons why these events might not be real - and I guarantee
- that when the results are *first* announced, most of these possibilities
- have not been scrutinized enough.
