$ZH$ production in gluon fusion: two-loop amplitudes with full top quark mass dependence
/ Chen, Long (Munich, Max Planck Inst. ; Aachen, Tech. Hochsch.) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jones, Stephen P. (CERN ; Durham U., IPPP) ; Kerner, Matthias (Zurich U.) ; Klappert, Jonas (RWTH Aachen U.) ; Schlenk, Johannes (PSI, Villigen)
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. [...]

A non-linear EFT description of $gg\to HH$ at NLO interfaced to POWHEG
/ Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jones, Stephen P. (CERN) ; Kerner, Matthias (Zurich U.) ; Scyboz, Ludovic (Oxford U., Theor. Phys.)
We present the implementation of Higgs boson pair production in gluon fusion within a non-linear Effective Field Theory framework containing five anomalous couplings for this process. The code, available within the POWHEG-BOX-V2, includes full NLO QCD corrections with massive top quarks. [...]

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).

Photon pair production in gluon fusion: Top quark effects around threshold

We present a calculation of the NLO QCD corrections to the loop-induced production of a photon pair through gluon fusion, including massive top quarks at two loops. The two-loop virtual amplitudes are computed via projecting onto a set of Lorentz structures related to linear polarisation states of external gauge bosons. [...]

Photon pair production in gluon fusion: Top quark effects at NLO with threshold matching
/ Chen, Long (Munich, Max Planck Inst.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Jahn, Stephan (Munich, Max Planck Inst.) ; Jones, Stephen P. (CERN) ; Kerner, Matthias (Zurich U.) ; Schlenk, Johannes (PSI, Villigen) ; Yokoya, Hiroshi (Korea Inst. Advanced Study, Seoul)
We present a calculation of the NLO QCD corrections to the loop-induced production of a photon pair through gluon fusion, including massive top quarks at two loops, where the two-loop integrals are calculated numerically. Matching the fixed-order NLO results to a threshold expansion, we obtain accurate results around the top quark pair production threshold. [...]

Double Higgs boson production at NLO: combining the exact numerical result and high-energy expansion

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. [...]

Recommended predictions for the boosted-Higgs cross section

In this note we study the inclusive production of a Higgs boson with large transverse momentum. We provide a recommendation for the inclusive cross section based on a combination of state of the art QCD predictions for the gluon-fusion and vector-boson-fusion channels. [...]

Higgs boson cross sections for the high-energy and high-luminosity LHC: cross-section predictions and theoretical uncertainty projections
/ Calderon Tazon, Alicia (Universidad de Cantabria and CSIC (ES)) ; Caola, Fabrizio (University of Durham (GB)) ; Campbell, John (Fermilab (US)) ; Francavilla, Paolo (Universita & INFN Pisa (IT)) ; Marchiori, Giovanni (Centre National de la Recherche Scientifique (FR)) ; Becker, Kathrin (Albert Ludwigs Universitaet Freiburg (DE)) ; Bertella, Claudia (Chinese Academy of Sciences (CN)) ; Bonvini, Marco (Sapienza Universita e INFN, Roma I (IT)) ; Chen, Xuan (Zuerich University (CH)) ; Frederix, Rikkert (Technische Universität Muenchen (DE)) et al.
This note summarizes the state-of-the-art predictions for the cross sections expected for Higgs boson production in the 27 TeV proton-proton collisions of a high-energy LHC, including a full theoretical uncertainty analysis. It also provides projections for the progress that may be expected on the timescale of the high-luminosity LHC and an assessment of the main limiting factors to further reduction of the remaining theoretical uncertainties..

Loopedia is a new database at https://loopedia.org for Feynman integrals, providing both bibliographic information as well as results made available by the community. Its bibliometry is complementary to that of Inspire or arXiv, as it allows to search for integrals by graph-theoretical specifications, e.g. [...]
