Top quark production at the Tevatron at NNLO.
We present results for top quark production at the Tevatron including next-to-nextto-
leading order (NNLO) soft-gluon corrections. We show the stability of the cross section
with respect to kinematics choice and scale when the...

Feb 08, 2010
I discuss charged Higgs production via the process bg ! tH− at the LHC. I
