Higgs-portal effective field theories are widely used as benchmarks in order to interpret
collider and astroparticle searches for dark matter (DM) particles. To assess the validity of …

The discovery of the Higgs boson has opened a new avenue for exploring physics beyond
the Standard Model. In this review, we discuss cosmological aspects of the simplest Higgs …

A bstract A search is presented for additional scalar (H) or pseudoscalar (A) Higgs bosons
decaying to a top quark pair in proton-proton collisions at a center-of-mass energy of 13 …

A bstract We investigate a possible realization of pseudo-Nambu-Goldstone (pNG) dark
matter in the framework of a singlet-extended 2 Higgs doublet model (S2HDM). pNG dark …

We study for the first time the collider reach on the derivative Higgs portal, the leading
effective interaction that couples a pseudo Nambu-Goldstone boson (pNGB) scalar Dark …

We construct families, and concrete examples, of simple extensions of the Standard Model
that can yield ultralight real or complex vectors or scalars with potential astrophysical …

A bstract We investigate the potential stochastic gravitational waves from first-order
electroweak phase transitions in a model with pseudo-Nambu-Goldstone dark matter and …

Persistent excesses in the spectra of gamma rays from the Galactic Center and cosmic ray
antiprotons can be explained by dark matter of mass 50–65 GeV annihilating into b quarks …

We reanalyze the effective field theory approach for the scenario in which the particles that
account for the dark matter (DM) in the universe are vector states that interact only or mainly …

We explore the gravitational wave spectrum generated by string-wall structures in an SO
(10)(S pin (10)) based scenario of pseudo-Goldstone boson dark matter (pGDM) particle …
