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..

Analytical parametrization and shape classification of anomalous HH production in EFT approach / Carvalho Antunes De Oliveira, Alexandra (Universita e INFN, Padova (IT)) ; Dall'Osso, Martino (Universita e INFN, Padova (IT)) ; De Castro Manzano, Pablo (Universita e INFN, Padova (IT)) ; Dorigo, Tommaso (Universita e INFN, Padova (IT)) ; Goertz, Florian (CERN) ; Gouzevitch, Maxime (Universite Claude Bernard-Lyon I (FR)) ; Tosi, Mia (CERN)
In this document we study the effect of anomalous Higgs boson couplings on non-resonant pair production of Higgs bosons (HH) at the LHC. We explore the space of the five parameters $\kappa_\lambda$, $\kappa_t$, $c_2$, $c_{g}$, and $c_{2g}$ in terms of the corresponding kinematics of the final state, and describe a suggested partition of the space into a limited number of regions featuring similar phenomenology in the kinematics of HH final state, along with a corresponding set of representative benchmark points.

Benchmark scenarios for low $\tan \beta$ in the MSSM / Bagnaschi, Emanuele (DESY) ; Frensch, Felix (Karlsruhe, Inst. Technol.) ; Heinemeyer, Sven (Cantabria Inst. of Phys.) ; Lee, Gabriel (Technion) ; Liebler, Stefan Rainer (DESY) ; Muhlleitner, Milada (Karlsruhe, Inst. Technol.) ; Mc Carn, Allison Renae (Michigan U.) ; Quevillon, Jeremie (King's Coll. London) ; Rompotis, Nikolaos (Seattle U.) ; Slavich, Pietro (Paris, LPTHE) et al.
The run-1 data taken at the LHC in 2011 and 2012 have led to strong constraints on the allowed parameter space of the MSSM. These are imposed by the discovery of an approximately SM-like Higgs boson with a mass of $125.09\pm0.24$~GeV and by the non-observation of SUSY particles or of additional (neutral or charged) Higgs bosons.

Recommendations for the interpretation of LHC searches for $H_5^0$, $H_5^{\pm}$, and $H_5^{\pm\pm}$ in vector boson fusion with decays to vector boson pairs / Zaro, Marco (Paris U., IV ; Paris, LPTHE) ; Logan, Heather (Ottawa Carleton Inst. Phys.)
We provide theory input for the interpretation of the LHC searches for the production of Higgs bosons $H_5^0$, $H_5^{\pm}$, and $H_5^{\pm\pm}$ that transform as a fiveplet under the custodial symmetry. We choose as a benchmark the Georgi-Machacek model, in which isospin-triplet scalars are added to the Standard Model Higgs sector in such a way as to preserve custodial SU(2) symmetry. [...]
