High-Q2 elastic ed scattering and QCD predictions.
In the framework of pertubative QCD it is argued that in the elastic edscattering at Q ∼ few (GeV/c) the light-cone-frame helicity-flip amplitudes could not be omitted. The obtained B A ratio of Rosenbluth structure functions is shown to be in a good agreement with experimental data. The high Q behavior of T20 is discussed. In a recent paper, Brodsky and Hiller [1] have made a general analysis ...
متن کاملPredictions with lattice QCD
In recent years, we used lattice QCD to calculate some quantities that were unknown or poorly known. They are the q dependence of the form factor in semileptonic D → Klν decay, the leptonic decay constants of the D and Ds mesons, and the mass of the Bc meson. In this paper, we summarize these calculations, with emphasis on their (subsequent) confirmation by measurements in ee, γp and p̄p collisions
متن کاملPredictions for Qcd from Supersymmetry
We review the construction of the effective Lagrangians of the VenezianoYankielowicz (VY) type for two non-supersymmetric theories containing one Dirac fermion in the two-index antisymmetric or symmetric representation of the gauge group (orientifold theories). Since these theories are planar equivalent, at N → ∞ to super Yang-Mill their effective Lagrangians coincides with the bosonic part of ...
متن کاملNLO QCD Predictions for W +3 jets
In this contribution we present results from the NLO computation of the production of a W boson in association with three jets in hadronic collisions. The results are obtained by combining two programs: BlackHat for the virtual one-loop matrix elements and Sherpa for the realemission contributions. We present results for the Tevatron and the LHC, and address the issue of the choice of a common ...
متن کاملConformal Expansions: A Template for QCD Predictions
The use of conformal expansions for predictions in quantum chromodynamics is discussed as a way to avoid renormalization scheme and scale ambiguities, as well as factorial growth of perturbative coefficients due to renormalons. Special emphasis is given to the properties of an assumed skeleton expansion and its relation to the Banks-Zaks expansion. The relation of BLM scale-setting to the skele...
