Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

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 …

Many extensions of the Standard Model predict the production of dark matter particles at the
LHC. Sufficiently light dark matter particles may be produced in decays of the Higgs boson …

A search for new phenomena in final states with hadronically decaying tau leptons, b-jets,
and missing transverse momentum is presented. The analyzed dataset comprises pp …

A combination of searches for top squark pair production using proton–proton collision data
at a center-of-mass energy of 13\, Te V Te at the CERN LHC, corresponding to an integrated …

A search for production of the supersymmetric partners of the top quark, top squarks, is
presented. The search is based on proton-proton collision events containing multiple jets, no …

A bstract The first collider search for dark matter arising from a strongly coupled hidden
sector is presented and uses a data sample corresponding to 138 fb− 1, collected with the …

This Letter presents a search for direct production of charginos and neutralinos via
electroweak interactions. The results are based on data from proton-proton collisions at a …

We study gravity wave production and baryogenesis at the electroweak phase transition in a
real singlet scalar extension of the Standard Model, including vectorlike top partners, to …

This paper presents a statistical combination of searches targeting final states with two top
quarks and invisible particles, characterised by the presence of zero, one or two leptons, at …
