The Standard Model of Particle Physics provides an excellent description of nature at distances larger than E-16 cm, or equivalently energies smaller than 100 GeV. However, there are reasons to believe that the Standard Model is incomplete and needs to be extended. For instance, the Standard Model does not provide any explanation to the observed fermion masses and mixing angles or to the large hierarchy between the electroweak scale and the Planck scale. It does not provide either any explanation for some observed cosmological parameters, such as the baryon asymmetry of the Universe, the relic density of dark matter or the amount of dark energy. Our research group considers extensions of the Standard Model that might account for these observations and we study their consequences for present and future experiments.

Abstract: We explore the possibility that the underlying flavour structure of the Standard Model could be determined by mass chains on a fractal geometry. We consider, as an example, the theory space on a…

Abstract: A strongly self-interacting component of asymmetric dark matter particles can form compact dark stars. The high dark matter density in these objects may allow significant dark matter annihilation into…
Journal of Cosmology and Astroparticle Physics
Abstract: The invisible decay of cold dark matter into a slightly lighter dark sector particle on cosmological time-scales has been proposed as a solution to the S 8 tension. In this work we discuss the…

Abstract: Astronomical and cosmological observations indicate that dark matter should interact very weakly with the electromagnetic radiation. Nevertheless, the existence of such interactions is not precluded…
Physics Letters B
Abstract: In some scenarios, the dark matter relic abundance is set by the semi-annihilation of two dark matter particles into one dark matter particle and one Standard Model particle. These semi-annihilations…
Journal of High Energy Physics
Abstract: We calculate the renormalization group equation (RGE) of the lepton-number-violating Weinberg operator with the particle content of the Standard Model (SM), thus completing the set of two-loop RGEs of…
Proceedings of Science
Abstract: A strongly self-interacting component of dark matter can lead to formation of compact objects. These objects (dark stars) can in principle be detected by emission of gravitational waves from…
European Physical Journal C
Abstract: This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of t-channel dark matter models, spanning minimal setups with a single dark…
Journal of High Energy Physics
Abstract: We study the decay of a heavy CP-even neutral Higgs into an on-shell Standard Model-like Higgs boson and two photons, H → hγγ, in the two-Higgs doublet model. We argue that the decay channel H → hγγ,…

Abstract: In the article “t-channel dark matter models – a whitepaper” published in EPJC, the name of one of the authors was incorrectly modified to Francesco D’Amico. The correct name is Francesco D’Eramo. The…
