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…
Muon Bremsstrahlung as a New Probe of Dark Sector at Neutrino Experiments
P. S. Bhupal Dev, Bhaskar Dutta, Aparajitha Karthikeyan +2
We show that muon bremsstrahlung provides a new production mechanism for light new physics at accelerator neutrino experiments beyond the meson kinematic limit. The intense, highly…
Producing the GeV Galactic Center Excess via Cosmic Ray-Dark Matter Scattering
Bhaskar Dutta, Debopam Goswami, Jason Kumar +2
In this work, we propose a novel mechanism for generating gamma rays from the Galactic Center via scattering of cosmic-ray protons off dark matter in the Milky Way halo, in contras…
Phasing out Dark Matter Isocurvature with Thermal Misalignment
Brian Batell, Akshay Ghalsasi, Subhajit Ghosh +1
Thermal misalignment provides an alternative to the standard misalignment mechanism for the cosmological production of scalar dark matter. In this framework, feeble couplings to pa…
