“…WimpSim does not account for modifications to the spectrum originating from the radiation of electroweak gauge bosons by the intermediate and final states of the decay process. These effects have been studied in [16]. Since both W ± and Z bosons decay promptly to produce high energy neutrinos, the net effect of these electroweak corrections is to harden the fluxes from the softer channels and enhance signal rate expectations.…”

“…Following Refs. [57,58], with electroweak corrections, the final state spectra obtained from 10 TeV to 100 TeV masses are extrapolated to PeV masses. Our choice of VHDM models is such that they include both hard and soft spectra, so our results can be viewed as reasonably model independent [25,29].…”

Testing the Dark Matter Scenario for PeV Neutrinos Observed in IceCube

Late time decay of very heavy dark matter is considered as one of the possible explanations for diffuse PeV neutrinos observed in IceCube. We consider implications of multimessenger constraints, and show that proposed models are marginally consistent with the diffuse γ-ray background data. Critical tests are possible by a detailed analysis and identification of the sub-TeV isotropic diffuse γ-ray data observed by Fermi and future observations of sub-PeV γ rays by observatories like HAWC or Tibet AS þ MD. In addition, with several-year observations by next-generation telescopes such as IceCube-Gen2, muon neutrino searches for nearby dark matter halos such as the Virgo cluster should allow us to rule out or support the dark matter models, independently of γ-ray and anisotropy tests.

“…Taking for simplicity the density to be constant and equal to the central density ρ = 151 g cm −3 (with a necessary shift of notation with respect to the previous section), the integrals can be evaluated explicitly yielding [335] n(r)…”

“…In first approximation this is just given by the difference between the minimal energy loss required to have v < v esc (r) after the scattering and the maximal energy loss in one scattering event, divided the maximal possible energy loss. In a more refined treatment, form factors must be introduced for each nuclear species in order to take into account the different response of nuclei depending on the energy [335]. The probability P i is weighted with the DM velocity distribution in the solar reference frame, which is related to the one in the galactic rest frame by…”

UNIVERSITÉ DE GENÈVE FACULTÉ DES SCIENCES AbstractThe problem of Dark Matter is one of the most longstanding problems in cosmology and particle physics, and surely one of the most interesting. A number of astrophysical and cosmological evidences point to the existence of a large amount of non luminous matter, whose nature is still a mistery. The simplest possible solution to this puzzle is in terms of new neutral and stable particles with weak-scale mass and couplings (named WIMPs for weakly interacting massive particles), which would not only reproduce naturally the observed cosmological Dark Matter abundance, but also fit very well in many well-motivated theories for physics beyond the Standard Model. In this thesis I discuss the present status of WIMP searches and of our understanding of the theoretical issues involved in them, with a particular emphasis to searches at the Large Hadron Collider.iii iv ABSTRACT List of publicationsPapers that appear in this thesis [1] ResuméLe problème de la matière noire (DM, de l'anglais Dark Matter) peut être résumé comme suit : plusieurs anomalies ont été observées, depuis 1933, à partir des échelles galactiques jusqu'à celles des plus large structures, qu'on ne peut pas expliquer que par l'existence de quelques éléments pas lumineux qui constituent plus de 80% de la masse totale des galaxies et des amas de galaxies, ou sinon par quelques modifications supplé-mentaires de la Relativité Générale. La quelle des deux solutions est correcte est encore matière à débat, même si une modification du contenu de la matière est généralement considéré plus probable. De plus, c'est un résultat bien établi le fait que les objets astrophysiques exotiques peuvent constituer seulement une petite partie du total de la Matière noire contenu dans l'Univers, avec seulement quelques petites fenêtres laissées ouvertes par l'observation astrophysique. à cause de ça, la solution la plus plausible du puzzle semble être dans la forme des particules subatomiques.Notre connaissance actuelle de la physique des particules est fondée sur l'ainsi nommé Modèle Standard (SM). La seule candidate de DM dans le Modèle Standard est le neutrino, mais, comme on verra dans le chapitre 1.3, les neutrinos ne peuvent pas constituer toute la DM, et l'introduction des nouvelles particules est necessaire. Deux faits très intéressants se présentent à ce moment. D'un côté, un simple calcul de l'abondance de la DM dans le modèle du Big Bang chaud indique qu'une particule avec une masse et une constante de couplage typiques des interactions faibles aurait la juste abondance aujourd'hui. Cette coïncidence est appelée le "WIMP miracle", pour weakly interacting massive particle. De l'autre côté, le SM souffre l'ainsi nommé "problème de la hiérarchie de l'échelle électrofaible", ça veut dire que l'échelle électrofaible est instable contre les corrections quantiques et, en supposant que le SM n'est que la limite de basse energie d'une physique plus fondamentale, peut-être à l'échelle de Planck, un choix ajusté finement...
