Perturbative Unitarity Constraints on Dark Matter Theories with Vector Portals [PDF]
, 2023 openScopo della tesi è lo studio di vincoli sui modelli di dark matter originati dall'unitarietà della matrice di scattering. L'elaborato affronta l'argomento introducendo le evidenze a supporto dell'esistenza della dark matter e presentando le wimps ...

Probable evidence for a transient mega-electron volt emission line in the GRB 221023A
Nature CommunicationsDetection of spectral line in gamma-ray bursts (GRBs) is importance for studying GRB physics, as it provides insights into the composition and physical conditions of the GRB environment.

A Dark-Matter Search Using the Final CDMS II Dataset and a Novel Detector of Surface Radiocontamination [PDF]
, 2012 Substantial evidence from galaxies, galaxy clusters, and cosmological scales suggests that ~85% of the matter of our universe is invisible. The missing matter, or "dark matter" is likely composed of non-relativistic, non-baryonic particles, which have ...

COMPOSITE DARK MATTER AND PUZZLES OF DARK MATTER SEARCHES [PDF]
International Journal of Modern Physics D, 2010 Positive results of dark matter searches in DAMA/ NaI and DAMA/LIBRA experiments, being put together with the results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter. Stable particles with charge -2, bound with primordial helium in O -helium "atoms" ( OHe ), represent a specific warmer than cold nuclear ...

The evolution of dark matter substructure [PDF]
, 2001 This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

New constraints on cosmic-ray boosted sub-Gev dark matter via light mediators
European Physical Journal C: Particles and FieldsTraditional direct detection experiments lack the sensitivity to probe the sub-GeV dark matter(DM), primarily due to the low energy of the expected nuclear recoils. In this work, we investigate cosmic-ray (CR) upscattering as a mechanism to accelerate DM

DARK MATTER, AND ITS DARKNESS [PDF]
International Journal of Modern Physics D, 2006 Assuming the validity of the general relativistic description of gravitation on astrophysical and cosmological length scales, we analytically infer that the Friedmann–Robertson–Walker cosmology with Einsteinian cosmological constant, and a vanishing spatial curvature constant, unambiguously requires a significant amount of dark matter.

The cosmological relevance of Fuzzy Dark Matter
, 2023 reservedThe concordance model of cosmology, the so-called Lambda CDM model, shows some shortcomes. However, if the dark matter considered in the model is characterized by an extremely low mass, then some of the imperfection could be explained.
