A novel model-marginalized cosmological bound on the QCD axion mass
Eleonora Di Valentino, Stefano Gariazzo, William Giarè +3
We present model-marginalized limits on mixed hot dark matter scenarios, which consider both thermal neutrinos and thermal QCD axions. A novel aspect of our analyses is the inclusi…
Non-unitary three-neutrino mixing in the early Universe
Stefano Gariazzo, Pablo Martínez-Miravé, Olga Mena +2
Deviations from unitarity in the three-neutrino mixing canonical picture are expected in many physics scenarios beyond the Standard Model. The mixing of new heavy neutral leptons w…
Model marginalized constraints on neutrino properties from cosmology
Eleonora di Valentino, Stefano Gariazzo, Olga Mena
We present robust, model-marginalized limits on both the total neutrino mass () and abundance () to minimize the role of parameterizations, priors and models…
Neutrino mass and mass ordering: No conclusive evidence for normal ordering
Stefano Gariazzo, Martina Gerbino, Thejs Brinckmann +8
The extraction of the neutrino mass ordering is one of the major challenges in particle physics and cosmology, not only for its implications for a fundamental theory of mass genera…
Heisenberg's uncertainty principle in the PTOLEMY project: a theory update
PTOLEMY Collaboration, A. Apponi, M. G. Betti +58
We discuss the consequences of the quantum uncertainty on the spectrum of the electron emitted by the -processes of a tritium atom bound to a graphene sheet. We analyze quantita…
White Paper on Light Sterile Neutrino Searches and Related Phenomenology
M. A. Acero, C. A. Argüelles, M. Hostert +169
This white paper provides a comprehensive review of our present understanding of experimental neutrino anomalies that remain unresolved, charting the progress achieved over the las…
Two sides of the same coin: sterile neutrinos and dark radiation. Status and perspectives
Maria Archidiacono, Stefano Gariazzo
The presence of light sterile neutrinos is one of the unanswered questions of particle physics. The cosmological counterpart is represented by dark radiation, i.e.\ any form of rad…
