Estimating High-Energy Neutrino Effective Areas from Muon Propagation

Stephan A. Meighen-Berger

Neutrino telescopes observe neutrinos through the muons produced by charged-current interactions. Most of those muons are born kilometers outside the detector, and how much energy…

Astrophysical Neutrino Sources as Colliders

Carlos A. Argüelles, P. S. Bhupal Dev, Bhaskar Dutta +6

High-energy neutrinos arise from processes at large center-of-mass energies, offering a window to test physics at comparable scales or beyond those accessible in collider experimen…

Dark matter energy exchange in stars orbiting supermassive black holes

Stephan A. Meighen-Berger, R. Andrew Gustafson, Nicole F. Bell +3

Stars on tight orbits around the supermassive black hole at the Galactic Center pass through regions where the dark matter~(DM) density may be strongly enhanced. We compute the orb…

Towards Measuring the CP-Violating Phase with Atmospheric Neutrinos

John F. Beacom, Nicole F. Bell, Matthew J. Dolan +2

We propose a new approach to measuring the CP-violating phase in neutrino mixing using atmospheric neutrinos, differing significantly from prior work. We develop an up-down flux ra…

New Multi-messenger Probe of Dark Matter-Nucleon Interactions from Ultra-high Energy Cosmic Ray Acceleration

Stephan A. Meighen-Berger, P. S. Bhupal Dev, Matheus Hostert

It has been suggested that the density of dark matter (DM) halo can be highly enhanced around supermassive black holes at the centers of massive galaxies. If real, these DM \emph{s…

Measuring the Cosmic Ray Spectrum with Next Generation Neutrino Detectors

Stephan A. Meighen-Berger, Jayden L. Newstead, Louis E. Strigari

We investigate the capabilities of upcoming kiloton-scale neutrino detectors, such as Hyper-Kamiokande, in determining the primary cosmic ray spectrum. These detectors provide full…

Can local White Dwarfs constrain Dark Matter interactions?

Pooja Bhattacharjee, Sandra Robles, Stephan A. Meighen-Berger +1

We investigate whether nearby white dwarfs (WDs) can constrain dark matter (DM) interactions with ordinary matter. As experimental sensitivity improves, driven by the Gaia mission,…

Extending the Dark Matter Reach of Water Cherenkov Detectors using Jupiter

Sandra Robles, Stephan A. Meighen-Berger

We propose the first method for water Cherenkov detectors to constrain GeV-scale dark matter (DM) below the solar evaporation mass. While previous efforts have highlighted the Sun…

Enhancing DUNE's solar neutrino capabilities with neutral-current detection

Stephan A. Meighen-Berger, Jayden L. Newstead, John F. Beacom +2

We show that the Deep Underground Neutrino Experiment (DUNE) has the potential to make a precise measurement of the total active flux of 8B solar neutrinos via neutral-current (NC)…

New Signal of Atmospheric Tau Neutrino Appearance: Sub-GeV Neutral-Current Interactions in JUNO

Stephan A. Meighen-Berger, John F. Beacom, Nicole F. Bell +1

We propose the first practical method to detect atmospheric tau neutrino appearance at sub-GeV energies, which would be an important test of oscillations and o…

Searching for Dark Matter Annihilation with IceCube and P-ONE

Kruteesh Desai, Ruohan Li, Stephan Meighen-Berger

We present a new search for weakly interacting massive particles utilizing ten years of public IceCube data, setting more stringent bounds than previous IceCube analysis on massive…

Dark Matter Hot Spots and Neutrino Telescopes

Stephan Meighen-Berger, Martina Karl

We perform a new dark matter hot spot analysis using ten years of public IceCube data. This analysis assumes dark matter self-annihilates to neutrino pairs and treats the productio…

New Constraints on Supersymmetry Using Neutrino Telescopes

Stephan Meighen-Berger, Matteo Agostini, Alejandro Ibarra +5

We demonstrate that megaton-mass neutrino telescopes are able to observe the signal from long-lived particles beyond the Standard Model, in particular the stau, the supersymmetric…
