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 …

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working
Group in the period 2014–2016. The main goal of the working group was to present the state …

Searches for new phenomena that consider signatures with τ leptons have gained great
interest in proton-proton (pp) collisions at the CERN LHC. The most prominent one among …

This Letter describes a search for Higgs boson pair production using the combined results
from four final states: bb γ γ, bb τ τ, bbbb, and bb VV, where V represents a W or Z boson …

A bstract In this work we revisit the existence of a strong first order electroweak phase
transition (SFOEWPT) and recent m W precision measurement in the Type-I and Type-II …

A search for the production of Higgs boson pairs in proton–proton collisions at a centre-of-
mass energy of 13 TeV is presented, using a data sample corresponding to an integrated …

We describe recent developments of the public computer code HiggsBounds. In particular,
these include the incorporation of LHC Higgs search results from Run 2 at a center-of-mass …

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 search for heavy pseudoscalar (A) and scalar (H) Higgs bosons decaying into a top quark
pair (tt¯) has been performed with 20.3 fb-1 of proton-proton collision data collected by the …

A search for Higgs-boson pair production in the $ b\bar {b} b\bar {b} $ final state is carried
out with 3.2 fb $^{-1} $ of proton--proton collision data collected at $\sqrt {s}= 13$ TeV with …
