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. The intense, highly collimated muon beam produced al…
Monophotons from Scalar Portal Dark Matter at Neutrino Experiments
Bhaskar Dutta, Debopam Goswami, Aparajitha Karthikeyan
In this work, we investigate monophoton signatures arising from dark matter via a scattering process that is mediated by a virtual scalar and a Stan…
DAMSA Experiment Conceptual Design White Paper
Prithak Bhattarai, Andrew Brandt, Alan Bross +41
DAMSA (DArk Messenger Searches at an Accelerator) is a novel short-baseline accelerator experiment aimed at probing short-lived physics processes, including searches for evidence o…
Drell-Yan Production of New Particles at Fixed-Target Experiments: Heavy Neutral Lepton as a Case Study
Francis M. Burk, P. S. Bhupal Dev, Bhaskar Dutta +3
We demonstrate the sensitivity of Drell-Yan production processes from deep inelastic scattering in searches for beyond-the-Standard Model (BSM) physics at fixed-target or beam-bump…
Opening up New Parameter Space for Sterile Neutrino Dark Matter
P. S. Bhupal Dev, Bhaskar Dutta, Srubabati Goswami +2
Sterile neutrinos are compelling dark matter (DM) candidates, yet the minimal production mechanism solely based on active ()-sterile () oscillations is excluded by astr…
