Some crosschecks

Mbb is interesting

New data

Jyothsna has processed the post-April2004 data.

I estimated the luminosity (based on the # of events)
+40/pb = total of 250/pb.

We need to calculate the actual luminosty on the jet and muon branches... need parentage files?

We still may be missing a few % of events...

Still crashed files?

Mbb

The Mbb distribution: mass of two leading b-tagged jets

Different spectrum for bbj(j) than fakes!

Gluon splitting... ?

Have we made the most of this?

This shows in a new way that we do understand our backgrounds

bbj(j)

fakes

Z(->bb)+jets

Events with >= 2 b-tags

Limits

I've processed all the data, using each set of optimized kinematic cuts from Jyothsna

Derived from maximizing S/sqrt(B) in Monte Carlo

In general, they don't help much, and often hurt...

I suggest we always use the loosest cuts (black points)

150 GeV cuts

130

110-120

90-100

Working on ...

Data set (luminosity)?
Monte Carlo -> bbj(j)?

Jet resolution?

Have these numbers been finalized?

Higgs width?

Maybe we just ignore mA=150 ?

Finish the D0Note...

Schedule:

I'm at CERN next week (!)

Then we have 2 weeks to polish the analysis and write a PRL...
