Is it a Standard Model Top
•
Does the cross-section
agree with QCD?
•
Does the mass agree with
SM
•
Are decays as expected?
Count e,
m,t
, jets, b-jets.
•
Check kinematics: pT &
angular distributions
Run II

QCD: a precise prediction for a change because it is calculable!!
Distinguish predictions
New physics:
top been produced in non standard way; top decaying non standard
