- Is that for CDF or D0? They have quite different efficiencies, so
- seeing one event at D0 for a given luminosity would correspond to
- a higher top mass, would it not?
-
- I think the real reason that they (D0) are not prepared to say much about
- consequences (even off the record) has to do with the fact that the
- detector efficiencies are a function of the event energy and topology,
- so the relation of the observed event to an overall t-tbar production
- rate is not known very well at this time (for D0 at least).
