Differential and Total Cross Sections for Top Pair and Single Top Production

Measurement of top quark pair differential cross sections

Measurements of normalized differential cross sections of top quark pair (tt̄) production are presented as a function of the mass, the transverse momentum and the rapidity of the tt̄ system in proton-proton collisions at center-of-mass energies of ffiffi s p 1⁄4 7 and 8 TeV. The data set corresponds to an integrated luminosity of 4.6 fb−1 at 7 TeV and 20.2 fb−1 at 8 TeV, recorded with the ATLAS d...

Renormalization-group improved calculation of top-quark production near threshold.

The top-quark cross section close to threshold in e(+)e(-) annihilation is computed including the summation of logarithms of the velocity at next-to-next-to-leading-logarithmic order in QCD. The remaining theoretical uncertainty in the normalization of the total cross section is at the few-percent level, an order of magnitude smaller than in previous next-to-next-to-leading order calculations. ...

Top Quark Cross Sections and Differential Distributions

I present results for the top quark pair total cross section and the top quark transverse momentum distribution at Tevatron and LHC energies. I also present results for single top quark production. All calculations include NNLO corrections from NNLL threshold resummation. TOP-ANTITOP PAIR PRODUCTION The leading order processes for top-antitop pair production are qq̄ → tt̄ (dominant at the Tevatro...
