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 …

The standard model of particle physics is an extremely successful theory of fundamental
interactions, but it has many known limitations. It is therefore widely believed to be an …

A bstract The existence of an axion-like particle (ALP) would induce anomalous scattering of
light by light. This process can be probed at the Large Hadron Collider in central exclusive …

We study the prospects for probing a gauge singlet scalar-driven strong first-order
electroweak phase transition with a future proton-proton collider in the 100 TeV range …

This review covers results on the production of all possible electroweak boson pairs and 2-to-
1 vector boson fusion at the CERN Large Hadron Collider (LHC) in proton-proton collisions …

Vector-boson scattering (VBS) processes probe the innermost structure of electroweak (EW)
interactions in the Standard Model (SM), and provide a unique sensitivity for new physics …

We explore strategies for probing hidden valley scenarios exhibiting confinement. Such
scenarios lead to a moderate multiplicity of light hidden hadrons for generic showering and …

Measuring the CP symmetry in the Higgs sector is one of the key tasks of the LHC and a
crucial ingredient for precision studies, for example in the language of effective Lagrangians …

A bstract We consider the immediate or near-term experimental opportunities offered by
some scenarios that could explain the new diphoton excess at the LHC. If the excess is due …

The measurement of Higgs couplings constitutes an important part of present standard
model precision tests at colliders. We show that modifications of Higgs couplings induce …
