Differential Cross Sections for Top-pair and Single-top Production

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

Top quark pair production and decay at a polarized photon collider

Top quark pair production by (polarized) γγ collisions offers an interesting testing ground of the Standard Model and its extensions. In this Letter we present results for differential cross sections of top quark pair production and decay including QCD radiative corrections. We take into account the full dependence on the top quark spins. We give analytic and numerical results for single and do...

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...

Higher-order Corrections to Top-antitop Pair and Single Top Quark Production

The top quark plays an important role in the Standard Model of particle physics as the most massive elementary particle, relevant to electroweak physics. The top was discovered via pair production [1, 2] and has also been more recently produced via single top [3, 4] channels at the Tevatron. On the theoretical side, QCD corrections are significant for top quark production and even higherorder c...

Fiducial, total and differential cross-section measurements of t-channel single top-quark production in pp collisions at 8 TeV using data collected by the ATLAS detector

Detailed measurements of t-channel single topquark production are presented. They use 20.2 fb−1 of data collected by the ATLAS experiment in proton–proton collisions at a centre-of-mass energy of 8 TeV at the LHC. Total, fiducial and differential cross-sections are measured for both top-quark and top-antiquark production. The fiducial crosssection is measured with a precision of 5.8% (top quark...
