Preliminary Hee analysis with 98D2
R.C./F.F./R.M./P.M. - 8/3/99

New features:

Data-MC  comparison: as usual, some disagreement, probably feedthrough from Bhabha's, not completely accounted by MC
Check: reject el. pairs with acopl. < 30 and energies > 40 GeV; the  comparison  is much more satisfactory

In the table, upper numbers are before and lower after the Bhabha rejection
Btag cut set at -1.8 (not relevant for 2D analysis)

Excess of data (initial cuts) explained

Lack of data (after 5C fit prob cut) possibly statistical (18.2 may fluctuate to 12 or less with 7% prob)
