Full NLO QCD predictions for Higgs-pair production in the 2-Higgs-Doublet Model
/ Baglio, J. (CERN ; QuantumBasel) ; Campanario, F. (Valencia U. ; Valencia U., IFIC) ; Glaus, S. (KIT, Karlsruhe, TP ; KIT, Karlsruhe, IKP) ; Mühlleitner, M. (KIT, Karlsruhe, TP) ; Ronca, J. (Rome III U. ; INFN, Rome3) ; Spira, M. (PSI, Villigen)
After the discovery of the Higgs boson in 2012 at the CERN Large Hadron Collider (LHC), the study of its properties still leaves room for an extended Higgs sector with more than one Higgs boson. 2-Higgs Doublet Models (2HDMs) are well-motivated extensions of the Standard Model (SM) with five physical Higgs bosons: two CP-even states $h$ and $H$, one CP-odd state $A$, and two charged states $H^\pm_{}$.

Full NLO QCD corrections to Higgs-pair production in the Standard Model and beyond
/ Baglio, Julien (CERN) ; Campanario, Francisco (Valencia U., IFIC ; Karlsruhe U., ITP) ; Glaus, Seraina (Karlsruhe U., ITP ; Karlsruhe U.) ; Mühlleitner, Milada Margarete (Karlsruhe U., ITP) ; Ronca, Jonathan (Valencia U., IFIC) ; Spira, Michael (PSI, Villigen)
Higgs-pair production is one of the targets of the high-luminosity LHC and of future hadron colliders, as it allows for a direct probe of the trilinear Higgs coupling and hence of the mechanism behind electroweak symmetry breaking. This contribution focuses on the impact of the full next- to-leading order QCD corrections to Higgs-pair production via gluon fusion, the main production mechanism at hadron colliders, in the Standard Model and in Two-Higgs-Doublet models.

$gg\to HH$: Combined Uncertainties
/ Baglio, J. (CERN) ; Campanario, F. (Valencia U., IFIC ; Karlsruhe U., ITP) ; Glaus, S. (Karlsruhe U., ITP ; Karlsruhe U.) ; Mühlleitner, M. (Karlsruhe U., ITP) ; Ronca, J. (Valencia U., IFIC) ; Spira, M. (PSI, Villigen)
In this note we discuss the combination of the usual renormalization and factorization scale uncertainties of Higgs-pair production via gluon fusion with the novel uncertainties originating from the scheme and scale choice of the virtual top mass. Moreover, we address the uncertainties related to the top-mass definition for different values of the trilinear Higgs coupling and their combination with the other uncertainties..

Higgs-Pair Production via Gluon Fusion at Hadron Colliders: NLO QCD Corrections
/ Baglio, J. (CERN) ; Campanario, F. (Valencia U., IFIC ; KIT, Karlsruhe, TP) ; Glaus, S. (KIT, Karlsruhe, TP ; KIT, Karlsruhe) ; Mühlleitner, M. (KIT, Karlsruhe, TP) ; Ronca, J. (Valencia U., IFIC) ; Spira, M. (PSI, Villigen) ; Streicher, J. (Tubingen U.)
Higgs-pair production via gluon fusion is the dominant production mechanism of Higgs-boson pairs at hadron colliders. In this work, we present details of our numerical determination of the full next-to-leading-order (NLO) QCD corrections to the leading top-quark loops. [...]

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.

Report from Working Group 1 : Standard Model Physics at the HL-LHC and HE-LHC
/ Azzi, P. (INFN, Padua) ; Farry, S. (Liverpool U.) ; Nason, P. (INFN, Milan Bicocca ; Milan Bicocca U.) ; Tricoli, A. (Brookhaven Natl. Lab.) ; Zeppenfeld, D. (KIT, Karlsruhe, TP) ; Abdul Khalek, R.

The successful operation of the Large Hadron Collider (LHC) and the excellent performance of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $pp$ collisions at center-of-mass energies of 7, 8 and 13 TeV as well as the giant leap in precision calculations and modeling of fundamental interactions at hadron colliders have allowed an extraordinary breadth of physics studies including precision measurements of a variety physics processes. The LHC results have so far confirmed the validity of the Standard Model of particle physics up to unprecedented energy scales and with great precision in the sectors of strong and electroweak interactions as well as flavour physics, for instance in top quark physics.

Anomalous couplings in WZ production beyond NLO QCD
/ Roth, Robin (Karlsruhe U., ITP) ; Campanario, Francisco (Valencia U., IFIC ; Valencia U.) ; Sapeta, Sebastian (CERN) ; Zeppenfeld, Dieter (KIT, Karlsruhe, TP)
We study WZ production with anomalous couplings at $\bar{n}$NLO QCD using the LoopSim method in combination with the Monte Carlo program VBFNLO. Higher order corrections to WZ production are dominated by additional hard jet radiation. [...]
