Measurement of the neutrino cross section across the TeV scale using IceCube data
Rasmi Hajjar, Mauricio Bustamante, Sergio Palomares-Ruiz
Neutrinos interact with matter exclusively through the weak force, resulting in extremely small cross sections that are difficult to measure. At TeV energies, neutrino-nucleon inte…
Self-Calibration of the Neutrino-Argon Cross Section with Solar Neutrinos
Rasmi Hajjar, Obada Nairat, John F. Beacom
The success of DUNE's MeV physics program depends upon high-precision knowledge of the charged-current (CC) cross section. While there are indirect constrain…
Dark energy and neutrinos along the cosmic expansion history
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Recent cosmological measurements are hinting that dark energy may evolve, with its equation of state, , even showing oscillatory patterns. In this work, we employ a…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Origin of cosmological neutrino mass bounds: background perturbations
Toni Bertólez-Martínez, Ivan Esteban, Rasmi Hajjar +2
The cosmological upper bound on the total neutrino mass is the dominant limit on this fundamental parameter. Recent observations-soon to be improved-have strongly tightened it, app…
Redshift Space Distortions corner interacting Dark Energy
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Despite the fact that the CDM model has been highly successful over the last few decades in providing an accurate fit to a broad range of cosmological and astrophysical observat…
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…
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…
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…
Heavy decaying dark matter at future neutrino radio telescopes
Marco Chianese, Damiano F. G. Fiorillo, Rasmi Hajjar +3
In the next decades, ultra-high-energy neutrinos in the EeV energy range will be potentially detected by next-generation neutrino telescopes. Although their primary goals are to ob…
Neutrino Mass Ordering at DUNE: an Extra -Bonus
Christoph A. Ternes, Stefano Gariazzo, Rasmi Hajjar +3
We study the possibility of extracting the neutrino mass ordering at the future Deep Underground Neutrino Experiment using atmospheric neutrinos, which will be available before the…
