Hello Andy
the Z->ee branching ratio is a factor of about three smaller than 
for W->enu.
The table in the paper (hep-ex/0107012) shows in each pT bin that the Z 
xsec is about one order of magnitude smaller.

The Z pT spectrum looks more or less alright. Overall the entries are 
about 30% lower than in data.
Similar for the W xsec (apart of the too steeply falling pT distribution)

I will produce some plots with comparison to data

	Lars
