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 flux of ultra-high-energy (UHE) neutrinos, produced by astrophysical sources at cosmological distances, is anticipated to exist and reach Earth. In this paper, we investigate the impact on the total…
Journal of Cosmology and Astroparticle Physics
Abstract: Dark matter decays into invisible particles can leave an imprint in large-scale structure surveys due to a characteristic redshift-dependent suppression of the power spectrum. We present a model with…
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: An unavoidable prediction of scenarios with Dark Matter (DM) self-interactions is the existence of number changing processes that convert n initial DM particles into m final ones (n → m processes),…
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…
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…

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…
