Addendum to: Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders [JHEP 10 (2019) 267]
/ Bizoń, Wojciech (Jagiellonian U.) ; Haisch, Ulrich (Munich, Max Planck Inst.) ; Rottoli, Luca (Zurich U.) ; Gillis, Zach (Chicago U. ; Chicago U., EFI) ; Moser, Brian (CERN) ; Windischhofer, Philipp (Chicago U. ; Chicago U., EFI ; Chicago U., Astron. Astrophys. Ctr. ; Chicago U., KICP)
We study inclusive double-Higgs boson production at the LHC and at the HL-LHC including variations of the trilinear and of the quartic Higgs boson self-couplings at next-to-leading order (NLO) in QCD with full top quark mass dependence. Our results include the two-loop contributions to the $gg \rightarrow HH$ amplitudes that involve a modified $h_4$ vertex calculated in arXiv:1810.04665. [...]

Bottom quark mass effects in associated $WH$ production with $H \to b\bar{b}$ decay through NNLO QCD
/ Behring, Arnd (KIT, Karlsruhe) ; Bizoń, Wojciech (Karlsruhe U., ITP ; KIT, Karlsruhe) ; Caola, Fabrizio (Oxford U., Theor. Phys.) ; Melnikov, Kirill (Karlsruhe U., ITP) ; Röntsch, Raoul (CERN)
We present a computation of NNLO QCD corrections to the production of a Higgs boson in association with a $W$ boson at the LHC followed by the decay of the Higgs boson to a $b\bar{b}$ pair. At variance with previous NNLO QCD studies of the same process, we treat $b$ quarks as massive. [...]

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.

Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders

We study the indirect constraints on the quartic Higgs self-coupling that arise from double-Higgs production at future hadron colliders. To this purpose, we calculate the two-loop contributions to the $gg \to hh$ amplitudes that involve a modified $h^4$ vertex. [...]

Fiducial distributions in Higgs and Drell-Yan production at N$^3$LL+NNLO
/ Bizoń, Wojciech (Oxford U., Theor. Phys.) ; Chen, Xuan (Zurich U.) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Rottoli, Luca (Oxford U., Theor. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin)
The perturbative description of certain differential distributions across a wide kinematic range requires the matching of fixed-order perturbation theory with resummation of large logarithmic corrections to all orders. We present precise matched predictions for transverse-momentum distributions in Higgs boson (H) and Drell-Yan pair (DY) production as well as for the closely related ${\phi^{*}_\eta}$ distribution at the LHC.

NNLOPS accurate associated HZ production with NLO decay ${\rm{H}} \to b\bar{b}$
/ Astill, William (Oxford U., Theor. Phys.) ; Bizoń, Wojciech (Oxford U., Theor. Phys.) ; Re, Emanuele (Annecy, LAPTH ; CERN) ; Zanderighi, Giulia (CERN ; Oxford U., Theor. Phys.)
We present a next-to-next-to-leading order (NNLO) accurate description of associated HZ production, followed by the Higgs boson decay into a pair of $b$-quarks treated at next-to-leading order (NLO), consistently matched to a parton shower (PS). The matching is achieved by performing reweighting of the $\texttt{HZJ-MiNLO}$ events, using multi-dimensional distributions that are fully-differential in the HZ Born kinematics, to the NNLO results obtained by using the $\texttt{MCFM-8.0}$ fixed-order calculation.

Momentum-space resummation for transverse observables and the Higgs $p_\perp$ at N$^3$LL+NNLO
/ Bizon, Wojciech (Oxford U., Theor. Phys.) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Rottoli, Luca (Oxford U., Theor. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin)
We present an approach to the momentum-space resummation of global, recursive infrared and collinear safe observables featuring kinematic zeros away from the Sudakov limit. In the hadro-production of a generic colour singlet, we consider the family of inclusive observables which do not depend on the rapidity of the radiation, prime examples being the transverse momentum of the singlet, and $\phi^*$ in Drell-Yan pair production.

Constraints on the trilinear Higgs coupling from vector boson fusion and associated Higgs production at the LHC
/ Bizon, Wojciech (Oxford U., Theor. Phys.) ; Gorbahn, Martin (Liverpool U., Dept. Math.) ; Haisch, Ulrich (CERN ; Oxford U., Theor. Phys.) ; Zanderighi, Giulia (CERN ; Oxford U., Theor. Phys.)
We examine the constraints on the trilinear Higgs coupling $\lambda$ that originate from associated ($Vh$) and vector boson fusion (VBF) Higgs production in $pp$ collisions in the context of the Standard Model effective field theory. The 1-loop contributions to $pp \to V h$ and $pp \to jj h$ that stem from insertions of the dimension-6 operator $O_6 = - \lambda \left (H^\dagger H \right )^3$ are calculated and combined with the ${\cal O} (\lambda)$ corrections to the partial decay widths of the Higgs boson.

NNLOPS accurate associated HW production
/ Astill, William (Oxford U., Theor. Phys.) ; Bizon, Wojciech (Oxford U., Theor. Phys.) ; Re, Emanuele (Oxford U., Theor. Phys. ; Annecy, LAPTH) ; Zanderighi, Giulia (CERN ; Oxford U., Theor. Phys.)
We present a next-to-next-to-leading order accurate description of associated HW production consistently matched to a parton shower. The method is based on reweighting events obtained with the HW plus one jet NLO accurate calculation implemented in POWHEG, extended with the MiNLO procedure, to reproduce NNLO accurate Born distributions.
