Measuring spin of top quark at hadronic collider
with F. Boudjema and W. Porod
with F. Boudjema and W. Porod
The spin of the top-quark is estimated through agreement of its production
cross section at Tevatron, but there is no direct mesurement of its spin. We
try to construct some simple observables involving the b quark and the lepton
from the decay of top quark to show its spin to be non-zero at hadronic
collider.
