Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The precision frontier in collider physics is being pushed at impressive speed, from both the
experimental and the theoretical side. The aim of this review is to give an overview of recent …

Searches are performed for nonresonant and resonant di-Higgs boson production in the bb¯
γ γ final state. The dataset used corresponds to an integrated luminosity of 139 fb-1 of proton …

A bstract A search for Higgs boson pair production in events with two b-jets and two τ-
leptons is presented, using a proton–proton collision dataset with an integrated luminosity of …

Without proper control of numerical and methodological errors in theoretical predictions at
the per mille level it is not possible to study the effect of input parameters in current hadron …

This Report summarizes the proceedings of the 2019 Les Houches workshop on Physics at
TeV Colliders. Session 1 dealt with (I) new developments for high precision Standard Model …

A search for heavy neutral lepton (N) production in K+→ e+ N decays using the data sample
collected by the NA62 experiment at CERN in 2017–2018 is reported. Upper limits of the …

A bstract A search for Higgs boson pair production via vector-boson fusion (VBF) in
the\(b\overline {b} b\overline {b}\) final state is carried out with the ATLAS experiment using …

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 …

Les Houches activities in 2021 were truncated due to the lack of an in-person component.
However, given the rapid progress in the field and the restart of the LHC, we wanted to …
