- But the uncertainty in top mass is something like +- 30 GeV if you
- lump together all of the experimental data on radiative corrections.
- So a top mass of 100 GeV would still be constistent with all the
- data and search limits to date. What would the expected yield for this
- event class be for such a top mass? Much higher than "less than one",
- no?
