Inelastic Signatures of Electroweak Dark Matter
Juri Smirnov, Spencer Griffith, John F. Beacom
Minimal dark matter extended to include a Majorana and a Dirac multiplet coupled through the Higgs --- the HC-MDM model --- provides a compelling and predictive framework. We show…
Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity
Spencer Griffith, Juri Smirnov, Laura Lopez-Honorez +1
Minimal electroweak dark matter models are compelling due to their simplicity, though calculations of their freezeout abundance are complicated by nonperturbative effects due to So…
Sub-GeV Dark Matter Detection with Dark Rates in Liquid Scintillators
Lillian Santos-Olmsted, Rebecca K. Leane, Carlos Blanco +1
It was recently shown that standard sub-GeV dark matter candidates can be effectively probed by large neutrino observatories via annual modulation of the total photomultiplier hit…
Towards First Detection of the Solar MSW Transition With JUNO
Obada Nairat, John F. Beacom, Kevin J. Kelly +1
Matter-induced neutrino flavor mixing (the Mikheyev-Smirnov-Wolfenstein, or MSW, effect) is a central prediction of the neutrino mixing framework, but it has not been conclusively…
New Spallation Background Rejection Techniques to Greatly Improve the Solar Neutrino Sensitivity of JUNO
Obada Nairat, John F. Beacom, Shirley Weishi Li
While the potential of the Jiangmen Underground Neutrino Observatory (JUNO) to measure solar neutrinos is known, realizing this potential requires new techniques to reduce detector…
Sub-GeV Dark Matter Direct Detection with Neutrino Observatories
Rebecca K. Leane, John F. Beacom
We present a new technique for sub-GeV dark matter (DM) searches and a new use of neutrino observatories. DM-electron scattering in an observatory can excite or ionize target molec…
Angular Distribution of Gamma Rays Produced in Proton-Proton Collisions
Spencer Griffith, John F. Beacom, Jung-Tsung Li +1
Accurate modeling of how high-energy proton-proton collisions produce gamma rays through the decays of pions and other secondaries is needed to correctly interpret astrophysical ob…
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)…
Neutron Tagging Can Greatly Reduce Spallation Backgrounds in Super-Kamiokande
Obada Nairat, John F. Beacom, Shirley Weishi Li
Super-Kamiokande's spallation backgrounds - the delayed beta decays of nuclides following cosmic-ray muons - are nearly all produced by the small fraction of muons with hadronic sh…
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…
First Detailed Calculation of Atmospheric Neutrino Foregrounds to the Diffuse Supernova Neutrino Background in Super-Kamiokande
Bei Zhou, John F. Beacom
The Diffuse Supernova Neutrino Background (DSNB) -- a probe of the core-collapse mechanism and the cosmic star-formation history -- has not been detected, but its discovery may be…
Distinctive nuclear signatures of low-energy atmospheric neutrinos
Anna M. Suliga, John F. Beacom
New probes of neutrino mixing are needed to advance precision studies. One promising direction is via the detection of low-energy atmospheric neutrinos (below a few hundred MeV), t…

Pawan Dhakal, Steven Prohira, Christopher V. Cappiello +3
We show that dark-matter candidates with large masses and large nuclear interaction cross sections are detectable with terrestrial radar systems. We develop our results in close co…
Towards Powerful Probes of Neutrino Self-Interactions in Supernovae
Po-Wen Chang, Ivan Esteban, John F. Beacom +2
Neutrinos remain mysterious. As an example, enhanced self-interactions (SI), which would have broad implications, are allowed. At the high neutrino densities within core-collaps…

The ultrahigh energy range of neutrino physics (above ), as yet devoid of detections, is an open landscape with challenges to be met and discoveries to…
Dimuons in Neutrino Telescopes: New Predictions and First Search in IceCube
Bei Zhou, John F. Beacom
Neutrino telescopes allow powerful probes of high-energy astrophysics and particle physics. Their power is increased when they can isolate different event classes, e.g., by flavor,…
Probing Secret Interactions of Astrophysical Neutrinos in the High-Statistics Era
Ivan Esteban, Sujata Pandey, Vedran Brdar +1
Do neutrinos have sizable self-interactions? They might. Laboratory constraints are weak, so strong effects are possible in astrophysical environments and the early universe. Obser…

(Not as) Big as a Barn: Upper Bounds on Dark Matter-Nucleus Cross Sections
Matthew C. Digman, Christopher V. Cappiello, John F. Beacom +2
Critical probes of dark matter come from tests of its elastic scattering with nuclei. The results are typically assumed to be model-independent, meaning that the form of the potent…
