Charge asymmetry in electron/positron energy loss in nuclear Bremsstrahlung
Journal of High Energy Physics, 2021 We calculate the leading Coulomb correction to the Bremsstrahlung energy loss in the electron-nucleus collisions for arbitrary energy of the incoming particle. This correction determines the charge asymmetry, i.e., the difference of electron and positron

The one-loop amplitudes for Higgs + 4 partons with full mass effects
Journal of High Energy Physics, 2020 We present compact analytic formulae for the one-loop amplitudes for Higgs + 4 parton scattering, 0 → ggggh, 0 → q ¯ $$ \overline{q} $$ qggh and 0 → q ¯ $$ \overline{q} $$ q q ¯ ′ $$ {\overline{q}}^{\prime } $$ q′h, mediated by a loop of massive coloured

Matching NLO QCD computations with parton shower simulations: the POWHEG method
Journal of High Energy Physics, 2007 The aim of this work is to describe in detail the POWHEG method, first suggested by one of the authors, for interfacing parton-shower generators with NLO QCD computations. We describe the method in its full generality, and then specify its features in two subtraction frameworks for NLO calculations: the Catani-Seymour and the Frixione-Kunszt-Signer ...

A first estimate of triply heavy baryon masses from the pNRQCD perturbative static potential [PDF]
, 2011 Within pNRQCD we compute the masses of spin-averaged triply heavy baryons using the now-available NNLO pNRQCD potentials and three-body variational approach.

NLO QCD+EW predictions for HV and HV +jet production including parton-shower effects
Journal of High Energy Physics, 2017 We present the first NLO QCD+EW predictions for Higgs boson production in association with a ℓν ℓ or ℓ + ℓ − pair plus zero or one jets at the LHC. Fixed-order NLO QCD+EW calculations are combined with a QCD+QED parton shower using the recently developed

Gluon fragmentation into quarkonium at next-to-leading order using FKS subtraction
Journal of High Energy Physics, 2019 We present the calculation at next-to-leading order (NLO) in α s of the fragmentation function of a gluon into heavy quarkonium in the color-octet spin-singlet S-wave channel.

Diphoton production in vector-boson scattering at the LHC at next-to-leading order QCD
Journal of High Energy Physics, 2020 In this paper, we present results at next-to-leading order (NLO) QCD for photon pair production in association with two jets via vector boson scattering within the Standard Model (SM), and also in an effective field theory framework with anomalous gauge ...

, 2002 I review recent results in QCD at high energy, emphasizing the role of higher-order computations, power corrections, and Monte Carlo simulations in the study of a few discrepancies between data and perturbative predictions, and discussing future ...

Next-to-leading order electroweak corrections to off-shell WWW production at the LHC
Journal of High Energy Physics, 2018 Triboson processes allow for a measurement of the triple and quartic couplings of the Standard Model gauge bosons, which can be used to constrain anomalous gauge couplings.

R2 vertices for the effective ggH theory
, 2013 We list all possible R2 Feynman rules needed in NLO computations involving couplings of Higgs and gluons mediated by an infinitely heavy top loop. They provide the rational contribution generated by the (d-4)-dimensional part of the amplitude, paving the
