Abstract The Large Hadron Collider (LHC) has confirmed the Higgs mechanism to generate
mass in the Standard Model (SM), making it attractive also to consider spontaneous …

Constraints on the Higgs boson self-coupling are set by combining double-Higgs boson
analyses in the bb¯ bb¯, bb¯ τ+ τ− and bb¯ γ γ decay channels with single-Higgs boson …

A bstract The results of a search for Higgs boson pair (HH) production in the WW* WW*,
WW* ττ, and ττττ decay modes are presented. The search uses 138 fb− 1 of proton-proton …

A future Higgs Factory will provide improved precision on measurements of Higgs couplings
beyond those obtained by the LHC, and will enable a broad range of investigations across …

A bstract We present a comprehensive study on Higgs pair production in various
archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet …

The discovery of the Higgs boson in 2012 provided confirmation of spontaneous
electroweak symmetry breaking as the mechanism by which fundamental particles gain …

A search for nonresonant Higgs boson pair production in the bbbb final state is presented.
The analysis uses 126 fb− 1 of pp collision data at s= 13 TeV collected with the ATLAS …

A dark sector is an interesting place where a strong first-order phase transition, observable
gravitational waves and/or a dark matter candidate could arise. However, the experimental …

A bstract In this work, we study the production of Higgs boson pairs at next-to-next-to-leading
order in QCD matched to parton showers, using the G eneva framework and working in the …

A bstract It is well-known that type II two Higgs doublet models (2HDMs) can struggle to
facilitate a strong first-order electroweak phase transition in the early universe whilst …
