Small-scale Cosmic Signatures of Feebly Interacting Massive Particles
Patrick Hager, Alexis Kassiteridis
Feebly Interacting Massive Particles (FIMPs), if they exist, should be notoriously difficult to detect even indirectly. In order to constrain them, we derive bounds for feeble theo…
Small-scale structure from charged leptophilia
Ottavia Balducci, Stefan Hofmann, Alexis Kassiteridis
We consider a charged leptophilic extension of the Standard Model of particle physics as a minimal dark sector. It accomodates a WIMP paradigm at the TeV-scale that is sufficient t…
Cosmic structure formation in a flavoured U dark sector at small scales
Ottavia Balducci, Stefan Hofmann, Alexis Kassiteridis
In this work we study the footprint of a secluded dark sector with a U gauge symmetry on the formation of cosmic structure at small scales. A single generation of d…
Small-scale structure from neutron dark decay
Georgios K. Karananas, Alexis Kassiteridis
It was recently proposed that the disagreement in the experimental measurements of the lifetime of the neutron might be eradicated if the neutron decays to particles responsible fo…
Cosmological singlet diagnostics of neutrinophilic dark matter
Ottavia Balducci, Stefan Hofmann, Alexis Kassiteridis
The standard model of particle physics is extended by adding a purely neutrinophilic dark sector. It is shown that theories which accommodate standard model neutrinos as dark radia…
On massless dyadic forms and no minimal coupling theorem
Alexis Kassiteridis
We use the spinor helicity formalism in order to derive the dyadic forms for massless fields of various spins. We also give an iterated form of this approach in case higher spin th…
