Next-to-Next-to-Next-to-Leading Order QCD Prediction for the Top Antitop S-Wave Pair Production Cross Section Near Threshold in e(+)e(-) Annihilation.
We present the third-order QCD prediction for the production of top antitop quark pairs in electron-positron collisions close to the threshold in the dominant S-wave state. We observe a significantExpand

Potential NRQCD and heavy-quarkonium spectrum at next-to-next-to-next-to-leading order
Abstract The next-to-next-to-next-to-leading order (N 3 LO) Hamiltonian of potential nonrelativistic QCD is derived. The complete matching of the Hamiltonian and the contribution from the ultrasoftExpand

Ultrasoft Effects in Heavy-Quarkonium Physics
Abstract In the framework of non-relativistic QCD, we consider a new class of radiative corrections, which are generated at next-to-next-to-next-to-leading order through the chromoelectric dipoleExpand

Top-Antitop Pair Production Close to Threshold Synopsis of Recent NNLO Results
Using non-relativistic effective theories, new next-to-next-to-leading order (NNLO) QCD corrections to the total $$t{\bar t}$$ production cross section at the Linear Collider have been calculatedExpand

What becomes of vortices in theories with flat directions
Abstract In many theories with flat directions of scalar potential, static vortex solutions do not exist for a generic choice of vacuum. In tow Euclidean dimensions, we find their substitutes —Expand

Determination of the top quark mass circa 2013: methods, subtleties, perspectives
We present an up-to-date overview of the problem of top quark mass determination. We assess the need for precision in the top mass extraction in the LHC era together with the main theoretical andExpand

Top quark threshold production in γγ collision in the next-to-leading order
Abstract The total cross section of the top quark-antiquark pair production near threshold in γγ collision is computed analytically up to the next-to-leading order in perturbative andExpand

Heavy light meson decay constant from QCD sum rules in three loop approximation
In this paper we compute the decay constant of the pseudo-scalar heavy-light mesons in the heavy quark effective theory framework of QCD sum rules. In our analysis we include the recently evaluatedExpand

Nonfactorizable QCD Effects in Higgs Boson Production via Vector Boson Fusion.
We discuss nonfactorizable QCD corrections to Higgs boson production in vector boson fusion at the Large Hadron Collider. We point out that these corrections can be computed in the eikonalExpand
