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. [...]

Top-bottom interference effects in Higgs plus jet production at the LHC
/ Lindert, Jonas (Durham U., IPPP) ; Melnikov, Kirill (KIT, Karlsruhe, TTP) ; Tancredi, Lorenzo (KIT, Karlsruhe, TTP) ; Wever, Chris (KIT, Karlsruhe, TTP ; KIT, Karlsruhe, IKP)
The next-to-leading order QCD corrections to the top-bottom interference contribution to $H+j$ production at the LHC are presented. The QCD corrections to the interference are large and similar to the QCD corrections to the top-mediated Higgs production cross section. [...]

The transverse momentum spectrum of weak gauge bosons at N$^3$LL$+$NNLO
/ Bizon, Wojciech (KIT, Karlsruhe, TTP ; KIT, Karlsruhe, IKP) ; Gehrmann-De Ridder, Aude (Zurich, ETH ; Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Rottoli, Luca (Milan Bicocca U. ; INFN, Milan Bicocca) ; Walker, Duncan M. (Durham U., IPPP)
We present accurate QCD predictions for the transverse momentum pT spectrum of electroweak gauge bosons at the LHC for 13 TeV collisions, based on a consistent combination of a NNLO calculation at large pT and N3LL resummation in the small pT limit. The inclusion of higher order corrections leads to substantial changes in the shape of the differential distributions, and the residual perturbative uncertainties are reduced to the few percent level across the whole transverse momentum spectrum.

Top-quark mass effects in $H$+jet and $H$+2 jets production
/ Chen, X. (KIT, Karlsruhe ; KIT, Karlsruhe, TP ; Zurich U.) ; Huss, A. (CERN) ; Jones, S.P. (Durham U., IPPP) ; Kerner, M. (KIT, Karlsruhe ; KIT, Karlsruhe, TP ; Zurich U.) ; Lang, J.-N. (Zurich U.) ; Lindert, J.M. (Sussex U.) ; Zhang, Hantian (Zurich U. ; KIT, Karlsruhe, TTP)
We present calculations of Higgs boson production via gluon-gluon fusion in association with one or two additional jets at next-to-leading order in QCD. The calculation of H+jet is exact in the treatment of the top-quark mass, whereas for the $H+$2 jets calculation the two-loop virtual amplitudes are approximated via a reweighting with leading-order mass effects, while keeping all top-quark mass effects in the real radiation contributions. [...]

A comparative study of Higgs boson production from vector-boson fusion
/ Buckley, A. (Glasgow U.) ; Chen, X. (Zurich U. ; KIT, Karlsruhe, TP ; KIT, Karlsruhe, SCC) ; Cruz-Martinez, J. (INFN, Milan ; Milan U.) ; Ferrario Ravasio, S. (Oxford U., Ctr.

(Sussex U.) et al.
The data taken in Run II at the LHC have started to probe Higgs boson production at high transverse momentum. Future data will provide a large sample of events with boosted Higgs boson topologies, allowing for a detailed understanding of electroweak Higgs boson plus two-jet production, and in particular the vector-boson fusion mode (VBF).

This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson self-coupling, with the wish to serve as a useful guide for the next years. The document discusses the theoretical status, including state-of-the-art predictions for di-Higgs cross sections, developments on the effective field theory approach, and studies on specific new physics scenarios that can show up in the di-Higgs final state.

We present results for the two-loop helicity amplitudes entering the NLO QCD corrections to the production of a Higgs boson in association with a $Z$-boson in gluon fusion. The two-loop integrals, involving massive top quarks, are calculated numerically. [...]

Double-real contribution to the quark beam function at N$^{3}$LO QCD
/ Melnikov, Kirill (KIT, Karlsruhe) ; Rietkerk, Robbert (KIT, Karlsruhe) ; Tancredi, Lorenzo (CERN) ; Wever, Christopher (KIT, Karlsruhe ; KIT, Karlsruhe, IKP)
We compute the master integrals required for the calculation of the double-real emission contributions to the matching coefficients of 0-jettiness beam functions at next-to-next-to-next-to-leading order in perturbative QCD. As an application, we combine these integrals and derive the double-real gluon emission contribution to the matching coefficient $I_{qq}(t,z)$ of the quark beam function..

Double Higgs boson production at NLO: combining the exact numerical result and high-energy expansion
/ Davies, Joshua (KIT, Karlsruhe, TTP) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Jones, Stephen P. (CERN) ; Kerner, Matthias (Zurich U.) ; Mishima, Go (KIT, Karlsruhe, TTP ; KIT, Karlsruhe, IKP) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP) ; Wellmann, David (KIT, Karlsruhe, TTP)
We consider the next-to-leading order QCD corrections to Higgs boson pair production, using our recent calculation of the form factors in the high-energy limit. We compute the virtual corrections to the partonic cross section, applying Pad\'e approximations to extend the range of validity of the high-energy expansion. [...]
