In this note we discuss the combination of usual renormalization and factorization scale uncertainties Higgs-pair production via gluon fusion with novel originating from scheme choice virtual top mass. Moreover, address related to top-mass definition for different values trilinear Higgs coupling their other uncertainties.
The 2011 Les Houches workshop was the first to confront LHC data. In two years since previous there have been significant advances in both soft and hard QCD, particularly areas of multi-leg NLO calculations, inclusion those calculations into parton shower Monte Carlos, tuning non-perturbative parameters Carlos. These proceedings describe theoretical that taken place, impact early data, for future development.

Higgs-pair production via gluon fusion is the dominant mechanism of Higgs-boson pairs at hadron colliders. In this work, we present details our numerical determination full next-to-leading-order (NLO) QCD corrections to leading top-quark loops. Since a loop-induced process order, NLO calculation requires massive two-loop diagrams with up four different mass/energy scales involved. With current methods, can only be done numerically, if no approximations are used. We discuss setup and...
We compute the $\mathcal{O}({\ensuremath{\alpha}}_{s})$ QCD corrections to charged triple vector boson production at a hadron collider, i.e., processes $pp\ensuremath{\rightarrow}ZZ{W}^{\ifmmode\pm\else\textpm\fi{}}+X$ and $pp\ensuremath{\rightarrow}{W}^{\ifmmode\pm\else\textpm\fi{}}{W}^{\ensuremath{\mp}}{W}^{\ifmmode\pm\else\textpm\fi{}}+X$. Intermediate Higgs exchange effects, spin correlations from leptonic decays, off shell contributions are all taken into account. Results implemented in...
We calculate next-to-leading order (NLO) QCD corrections to electroweak Higgs plus three jet production. Both vector boson fusion (VBF) and Higgs-strahlung type contributions are included along with all interferences. The calculation is implemented within the Matchbox NLO framework of Herwig++ event generator.
We present the calculation of full next-to-leading order (NLO) QCD corrections to Higgs boson pair production via gluon fusion at LHC, including exact top-mass dependence in two-loop virtual and one-loop real corrections. This is first independent cross-check NLO presented literature before. Our relies on numerical integrations Feynman integrals, stabilised with integration-by-parts a Richardson extrapolation narrow width approximation. results for total cross section as well invariant...
In this paper, we address the question of whether almost four standard deviations difference between theory and experiment for muon anomalous magnetic moment ${a}_{\ensuremath{\mu}}$ can be explained as a higher-order Standard Model perturbation effect in pion form factor measurements. This has, until now, remained open, obscuring source discrepancies We calculate last radiative corrections extraction factor, which were believed to potentially substantial enough explain data within Model....
The computation of the NLO QCD corrections to cross sections for W+W- gamma and ZZgamma production in hadronic collisions is presented. We consider case a real photon final state, but include full leptonic decays W Z bosons. Numerical results LHC Tevatron are obtained through fully flexible parton level Monte Carlo based on structure VBFNLO program, allowing an easy implementation arbitrary cuts distributions. show dependence scale variations integrated provide evidence that strongly modify...
Abstract Vbfnlo is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), QCD-induced single and double production plus two jets, triple (plus jet) in hadronic collisions at next-to-leading order (NLO) strong coupling constant, as well Higgs three jet via gluon one-loop level. For new version – Version 3.0 several major enhancements have been included. An interface according to Binoth Les Houches Accord (BLHA) has added all VBF di/tri-boson processes...

We consider case real photons final state, but include full leptonic decays W. Numerical results LHC and Tevatron are obtained through a parton level Monte Carlo based on structure VBFNLO program, allowing an easy implementation general cuts distributions. show dependence scale variations integrated provide evidence fact that NLO QCD strongly modify LO predictions...
We present a calculation of the $\mathcal{O}({\ensuremath{\alpha}}_{s})$ QCD corrections to production $Z$ boson in association with two photons and triple-photon at hadron colliders. All final-state are taken as real. For boson, we consider decays both into charged leptons neutrinos including all off-shell effects. Numerical results obtained via Monte Carlo program based on structure VBFNLO package. This allows us implement general cuts distributions particles. find that next-to-leading...
In high energy hadronic collisions, a scalar or pseudoscalar Higgs boson, $\ensuremath{\Phi}=H$, $A$, can be efficiently produced via gluon fusion, which is mediated by heavy quark loops. this paper, we consider double real emission corrections to $\ensuremath{\Phi}=A$ production, lead plus two-jet final state, at order ${\ensuremath{\alpha}}_{s}^{4}$. Full mass effects are considered in the calculation of scattering amplitudes for $\mathcal{C}\mathcal{P}$-odd boson as induced triangle-,...
In this letter we report on a calculation of W gamma + jet production at next-to-leading order QCD. We include the leptonic decays and take into account all off-shell finite width effects. This is first computation which falls category triboson+jet total find sizable corrections with nontrivial phase space dependencies. Therefore, our results are important for phenomenological analyses such as extraction anomalous electroweak quartic couplings from inclusive hadron collider data.
We report on the calculation of W(±) Zjj production with leptonic decays at hadron-hadron colliders next-to-leading order in QCD. These processes are important both to test quartic gauge couplings standard model and because they constitute relevant backgrounds beyond physics searches. Our results show that corrections reduce significantly scale uncertainties have a nontrivial phase space dependence.
We present a study of ${W}^{+}{W}^{+}jj$ and ${W}^{\ensuremath{-}}{W}^{\ensuremath{-}}jj$ production including leptonic decays in hadron-hadron collisions. The full electroweak QCD induced contributions their interferences are calculated at leading order. find that, for inclusive cuts, the interference effects can be large if jets produced with transverse momentum where, however, rate is suppressed. also discuss vector-boson-fusion cuts show validity approximation. next-to-leading order...
