Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

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 bstract A search for Higgs bosons that decay into a bottom quark-antiquark pair and are
accompanied by at least one additional bottom quark is performed with the CMS detector …

Does the value of the Higgs mass parameter affect the expectation value of local operators
in the Standard Model? For essentially all local operators the answer to this question is “no” …

A bstract We investigate the bounds on light pseudoscalars that arise from a variety of
collider searches. Special attention is thereby devoted to the mass regions [3, 5] GeV and [9 …

A bstract We study the potential of future lepton colliders, running at the Z-pole and above,
and the High-Luminosity LHC to search for the relaxion and other light scalars ϕ. We …

A bstract We discuss universal signals of consistent models of pseudoscalar mediators for
collider searches for Dark Matter. Keeping only the degrees of freedom that can not be …

A bstract The Standard Model (SM)-like couplings of the observed Higgs boson impose
strong constraints on the structure of any extended Higgs sector. We consider the theoretical …

In the framework of the type II two-Higgs-doublet model with a singlet scalar dark matter S,
we study the dark matter observables, the electroweak phase transition, and the …

A bstract A search for resonances in the mass range 12–70 GeV produced in association
with ab quark jet and a second jet, and decaying to a muon pair, is reported. The analysis is …
