Four-lepton production in gluon fusion at NLO matched to parton showers / Alioli, Simone (Milan Bicocca U.) ; Ferrario Ravasio, Silvia (Oxford U., Theor. Phys.) ; Lindert, Jonas M. (Sussex U., Astron. Ctr.) ; Röntsch, Raoul (CERN)
We present a calculation of the next-to-leading order (NLO) QCD corrections to gluon-induced electroweak gauge boson pair production, $gg \to ZZ$ and $gg \to W^+W^-$, matched to the PYTHIA8 parton shower in the POWHEG approach. The calculation consistently incorporates the continuum background, the Higgs-mediated $gg\to H^* \to VV$ process, and their interference. [...]

Precise predictions for boosted Higgs production / Becker, Kathrin (Freiburg U.) ; Caola, Fabrizio (Oxford U., Theor. Phys.) ; Massironi, Andrea (CERN ; INFN, Milan Bicocca) ; Mistlberger, Bernhard (MIT) ; Monni, Pier Francesco (CERN) ; Chen, Xuan (Zurich U.) ; Frixione, Stefano (INFN, Genoa) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Hamilton, Keith (University Coll. London) et al.
Inclusive Higgs boson production at large transverse momentum is induced by different production channels. We focus on the leading production through gluon fusion, and perform a consistent combination of the state of the art calculations obtained in the infinite-top-mass effective theory at next-to-next-to-leading order (NNLO) and in the full Standard Model (SM) at next-to-leading order (NLO).

Higher-Order QCD corrections to Higgs Boson transverse-momentum distribution / Caola, Fabrizio (Oxford U.) ; Lindert, Jonas M (Sussex U.) ; Melnikov, Kirill (KIT, Karlsruhe) ; Monni, Pier F (CERN) ; Tancredi, Lorenzo (Oxford U.) ; Wever, Chris (Munich, Tech. U.) ; Kudashkin, Kirill (Milan U.)
We present up-to-date Standard Model theory predictions for the Higgs transverse-momentum (p⊥) distribution. In the region of intermediate values of transverse momenta we present the NNLL+NLO QCD predictions including both top and bottom quark contributions. [...]

Accurate simulation of W, Z and Higgs boson decays in Sherpa / Krauss, Frank (Durham U., IPPP) ; Lindert, Jonas M. (Durham U., IPPP) ; Linten, Robin (Durham U., IPPP) ; Schönherr, Marek (CERN)
We discuss the inclusion of next-to-next-to leading order electromagnetic and of next-to leading order electroweak corrections to the leptonic decays of weak gauge and Higgs bosons in the SHERPA event generator. To this end, we modify the Yennie-Frautschi-Suura scheme for the resummation of soft photon corrections and its systematic improvement with fixed-order calculations, to also include the effect of virtual corrections due to the exchange of weak gauge bosons.

Bottom-quark effects in Higgs production at intermediate transverse momentum / Caola, Fabrizio (Durham U., IPPP) ; Lindert, Jonas M. (Durham U., IPPP) ; Melnikov, Kirill (KIT, Karlsruhe, TTP) ; Monni, Pier Francesco (CERN) ; Tancredi, Lorenzo (CERN) ; Wever, Christopher (KIT, Karlsruhe, TTP ; KIT, Karlsruhe, IKP)
We provide a precise description of the Higgs boson transverse momentum distribution including top and bottom quark contributions, that is valid for transverse momenta in the range mb < pt < mt, where mb and mt are the bottom and top quark masses. This description is based on a combination of fixed next-to-leading order (NLO) results with next-to-next-to-leading logarithmic (NNLL) transverse momentum resummation. [...]

Higgs boson pair production at NNLO with top quark mass effects / Grazzini, Massimiliano (Zurich U.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Jones, Stephen (Munich, Max Planck Inst.) ; Kallweit, Stefan (CERN) ; Kerner, Matthias (Munich, Max Planck Inst.) ; Lindert, Jonas M. (Durham U., IPPP) ; Mazzitelli, Javier (Zurich U.)
We consider QCD radiative corrections to Higgs boson pair production through gluon fusion in proton collisions. We combine the exact next-to-leading order (NLO) contribution, which features two-loop virtual amplitudes with the full dependence on the top quark mass $M_t$, with the next-to-next-to-leading order (NNLO) corrections computed in the large-$M_t$ approximation.

Multi-jet merged top-pair production including electroweak corrections / Gütschow, Christian (University Coll. London) ; Lindert, Jonas M. (Durham U., IPPP) ; Schönherr, Marek (CERN)
We present theoretical predictions for the production of top-quark pairs in association with jets at the LHC including electroweak (EW) corrections. First, we present and compare differential predictions at the fixed-order level for $t \bar t$ and $t \bar t+$jet production at the LHC considering the dominant NLO EW corrections of order $\mathcal{O}(\alpha_S^2 \alpha)$ and $\mathcal{O}(\alpha_S^3 \alpha)$ respectively together with all additional subleading Born and one-loop contributions.
