We review the physics opportunities of the Future Circular Collider, covering its e+ e-, pp, ep
and heavy ion programmes. We describe the measurement capabilities of each FCC …

We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

and heavy ion programmes. We describe the measurement capabilities of each FCC …

What is the maximum possible strength of a first-order electroweak phase transition and the
resulting gravitational wave (GW) signal? While naively one might expect that supercooling …

We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

We review the production of gravitational waves by an electroweak first-order phase
transition. The resulting signal is a good candidate for detection at next-generation …

A bstract Measuring the shape of the Higgs boson potential is of paramount importance, and
will be a challenging task at current as well as future colliders. While the expectations for the …

A bstract We analyse a simple extension of the SM with just an additional scalar singlet
coupled to the Higgs boson. We discuss the possible probes for electroweak baryogenesis …

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 production of pairs of Higgs bosons at hadron colliders provides unique information on
the Higgs sector and on the mechanism underlying electroweak symmetry breaking (EWSB) …
