Dark matter interactions with electrons or protons during the early Universe leave imprints
on the cosmic microwave background and the matter power spectrum, and can be probed …

It is commonly conjectured that dark matter is a charge neutral fundamental particle.
However, it may still have minute photon-mediated interactions through millicharge, or …

Beyond the Standard Model electromagnetic properties of neutrinos may lead to copious
production of sterile neutrinos in the hot and dense core of a core-collapse supernova. In …

Despite being mostly secluded, dark sector particles may feebly interact with photons via a
small mass-dimension 4 millicharge, a mass-dimension 5 magnetic and electric dipole …

A bstract The Standard Model Effective Field Theory (SMEFT) and the Low Energy Effective
Field Theory (LEFT) can be extended by adding additional spin 0, 1/2 and 1 dark matter …

We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest
experimental results using the global fitting framework GAMBIT. We perform a global …

We consider the upscattering of atmospheric neutrinos in the interior of Earth producing
heavy neutral leptons (HNLs) which subsequently decay inside large volume detectors (eg …

A bstract We present an effective field theory describing the relevant interactions of the
Standard Model with an electrically neutral particle that can account for the dark matter in the …

Mass dimension one fermionic fields are prime candidates to describe dark matter, due to
their intrinsic neutral nature, as they are constructed as eigenstates of the charge …

We perform a model independent study of freeze-in of massive particle dark matter (DM) by
adopting an effective field theory framework. Considering the dark matter to be a gauge …
