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…
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 constrai…
Building an AI-native Research Ecosystem for Experimental Particle Physics: A Community Vision
Thea Klaeboe Aarrestad, Alaa Abdelhamid, Haider Abidi +457
Experimental particle physics seeks to understand the universe by probing its fundamental particles and forces and exploring how they govern the large-scale processes that shape co…
First Observations of Solar Halo Gamma Rays Over a Full Solar Cycle
Tim Linden, Jung-Tsung Li, Bei Zhou +4
We analyze 15 years of Fermi-LAT data and produce a detailed model of the Sun's inverse-Compton scattering emission (solar halo), which is powered by interactions between ambient c…
Convection-Driven Multi-Scale Magnetic Fields Determine the Observed Solar-Disk Gamma Rays
Jung-Tsung Li, Mahboubeh Asgari-Targhi, John F. Beacom +1
The solar disk is a continuous source of GeV--TeV gamma rays. The emission is thought to originate from hadronic Galactic cosmic rays (GCRs) interacting with the gas in the photosp…
