Mass fits
Mass fits :
| Maximum-likelihood fits to the CC-EC and EC-EC Z events.
|
| Maximum-likelihood fit to the mt distributions of the W events.
We obtain 80.766 +/- 0.108 GeV from the
transverse mass fit.
|
| Maximum-likelihood fits to the electron pt distributions of the
W events.
We obtain 80.587 +/- 0.125 GeV from pt(e) fit.
|
| Maximum-likelihood fits to the pt(nu) distributions of the
W events.
We obtain 80.726 +/- 0.163 GeV from pt(nu) fit.

As a cross check, we use the Z -> ee sample ignoring one electron to determine
the Z mass from the transverse mass distribution. For this study,
an EC electron was always retained. We find mZ = 91.074 +/- 0.299 GeV (EC-EC)
and 92.074 +/- 0.895 GeV (CC-EC).
| Maximum-likelihood fits to the transverse mass
distributions of the EC-CC and EC-EC Z events, where the transverse mass
is reconstructed using the forward electron(s) and the recoil.
