Results from 161+172 GeV |
Cross-sections and Asymmetries
Hadronic and Leptonic cross-sections vs energy (preliminary) :
|
| Cross-section
|
Variation of the cross-sections for hadrons, electrons, muons and taus
as function of the energy.
The data correspond to DELPHI measurements at the Z0 peak,
at 130-136 GeV (1995) and at 161 and 172 GeV (1996).
Forward-backward Asymmetries vs energy (preliminary) :
|
| Leptonic AFB
|
Variation of the forward-backward asymmetries for electrons, muons and taus
as function of the energy.
The data correspond to DELPHI measurements at the Z0 peak,
at 130-136 GeV (1995) and at 161 and 172 GeV (1996).
Comparison of Hadronic and Leptonic cross sections with ZFITTER predictions
(preliminary) :
|
| 172 GeV
|
Relative deviation between the measurements and the ZFITTER 5.0 prediction
from the runs at 130-136 GeV (1995) and at 161 and 172 GeV (1996).
s' Distributions
s' Distributions for Hadrons and for Leptons (preliminary) :
| 
|
| Hadrons, 172 GeV
| Leptons, 172 GeV
|
Ratio sqrt(s')/sqrt(s) for events (dots) and the expectation (histogram)
for hadrons, muons and taus at 172 GeV.
Backgrounds are displayed in a different colour in the histograms.
Contact Interactions
(preliminary) :
|
| 172 GeV
