Shedding light on the tension with supernova neutrinos
Rasmi Hajjar, Sergio Palomares-Ruiz, Olga Mena
One long-standing tension in the determination of neutrino parameters is the mismatched value of the solar mass square difference, , measured by different experiments: t…
Quantifying the tension between cosmological and terrestrial constraints on neutrino masses
Stefano Gariazzo, Olga Mena, Thomas Schwetz
The sensitivity of cosmology to the total neutrino mass scale is approaching the minimal values required by oscillation data. We study quantitatively possible tensions betwe…
Earth tomography with supernova neutrinos at future neutrino detectors
Rasmi Hajjar, Olga Mena, Sergio Palomares-Ruiz
Earth neutrino tomography is a realistic possibility with current and future neutrino detectors, complementary to geophysics methods. The two main approaches are based on either pa…
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…
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…
Synergy between cosmological and laboratory searches in neutrino physics
Martina Gerbino, Evan Grohs, Massimiliano Lattanzi +21
The intersection of the cosmic and neutrino frontiers is a rich field where much discovery space still remains. Neutrinos play a pivotal role in the hot big bang cosmology, influen…
An absolute mass measurement with the DUNE experiment
Federica Pompa, Francesco Capozzi, Olga Mena +1
Time of flight delay in the supernova neutrino signal offers a unique tool to set model-independent constraints on the absolute neutrino mass. The presence of a sharp time structur…

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor physics, and its determination may provide the key to establish the relationship among the…
Neutrino masses and their ordering: Global Data, Priors and Models
S. Gariazzo, M. Archidiacono, P. F. de Salas +3
We present a Bayesian analysis of the combination of current neutrino oscillation, neutrinoless double beta decay and CMB observations. Our major goal is to carefully investigate t…
Non-standard interactions with high-energy atmospheric neutrinos at IceCube
Jordi Salvado, Olga Mena, Sergio Palomares-Ruiz +1
Non-standard interactions in the propagation of neutrinos in matter can lead to significant deviations from expectations within the standard neutrino oscillation framework and atmo…
