QCD field strength correlator at the next-to-leading order
The gauge invariant two-point correlation function of the gauge field strength tensor is calculated in perturbation theory at the next-to-leading order. Besides a direct calculation in perturbative QCD we also present a derivation of the correlation function in the heavy quark effective theory. Our results are briefly compared with recent determinations of the field strength correlator on the l...
متن کاملTop-quark decay at next-to-next-to-leading order in QCD.
We present the complete calculation of the top-quark decay width at next-to-next-to-leading order in QCD, including next-to-leading electroweak corrections as well as finite bottom quark mass and W boson width effects. In particular, we also show the first results of the fully differential decay rates for the top-quark semileptonic decay t → W(+)(l(+)ν)b at next-to-next-to-leading order in QCD....
متن کاملEffects of supersymmetric QCD in hadronic Higgs production at next-to-next-to-leading order
An estimate of the next-to-next-to-leading order ~NNLO! supersymmetric QCD effects for Higgs production at hadron colliders is given. Assuming an effective gluon-Higgs interaction, these corrections enter only in terms of process-independent, factorizable terms. We argue that the current knowledge of these terms up to NLO is sufficient to derive the NNLO hadronic cross section within the limita...
متن کاملHiggs Boson pair production at next-to-next-to-leading order in QCD.
We compute the next-to-next-to-leading order QCD corrections for standard model Higgs boson pair production inclusive cross section at hadron colliders within the large top-mass approximation. We provide numerical results for the LHC, finding that the corrections are large, resulting in an increase of O(20%) with respect to the next-to-leading order result at c.m. energy sqrt[sH]=14 TeV. We ob...
متن کاملThe Infrared Behavior of One-Loop QCD Amplitudes at Next-to-Next-to-Leading Order
We present universal factorization formulas describing the behavior of one-loop QCD amplitudes as external momenta become either soft or collinear. Our results are valid to all orders in the dimensional regularization parameter, ǫ. Terms through O(ǫ2) can contribute in infrared divergent phase space integrals associated with next-to-next-to-leading order jet cross-sections.
