Dark Matter abundance via thermal decays and leptoquark mediators

Benedetta Belfatto, Dario Buttazzo, Christian Gross +5

We explore a new mechanism for reproducing the Dark Matter (DM) abundance: scatterings of one DM particle on light Standard Model particles. Strong bounds on its decays can be sati…

Constraints on heavy decaying dark matter with current gamma-ray measurements

Marco Chianese, Damiano F. G. Fiorillo, Rasmi Hajjar +2

Among the several strategies for indirect searches of dark matter, one very promising one is to look for the gamma-rays from decaying dark matter. Here we use the most up-to-date u…

Sensitivity of KM3NeT to Violation of Equivalence Principle

Marco Chianese, Damiano F. G. Fiorillo, Gianpiero Mangano +3

The symmetry of the theory of relativity under diffeomorphisms strongly depends on the equivalence principle. Violation of Equivalence Principle (VEP) can be tested by looking for…

Direct Detection of Light Dark Matter from Evaporating Primordial Black Holes

Roberta Calabrese, Marco Chianese, Damiano F. G. Fiorillo +1

The direct detection of sub-GeV dark matter interacting with nucleons is hampered by the low recoil energies induced by scatterings in the detectors. This experimental difficulty i…

Towards baryogenesis via absorption from Primordial Black Holes

Antonio Ambrosone, Roberta Calabrese, Damiano F. G. Fiorillo +2

Recently Dolgov and Pozdnyakov proposed a new baryogenesis mechanism in which baryon asymmetry is produced without violating baryon number at the Lagrangian level. In this scenario…

Naturalness of lepton non-universality and muon g-2

Giacomo Cacciapaglia, Corentin Cot, Francesco Sannino

We show that the observed anomalies in the lepton sector can be explained in extensions of the Standard Model that are natural and, therefore, resolve the Higgs sector hierarchy pr…
