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…
Prying Open the Dark Sector Window with SBND Off-Target Mode
Bhaskar Dutta, Debopam Goswami, Aparajitha Karthikeyan +4
Accelerator-based neutrino experiments with high-intensity proton beams and advanced detector technologies provide a powerful and complementary approach to probing physics beyond t…
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…
Dark Matter-Induced Nuclear De-Excitation at SBND with Ab Initio Nuclear Theory
Bhaskar Dutta, Debopam Goswami, Baishan Hu +2
We explore the sensitivity of the Short-Baseline Near Detector (SBND) experiment to light dark matter using MeV-scale electromagnetic activity. Inelastic scattering of dark matter…
Dirt/Detector/Dump: Complementary BSM production at Short-Baseline Neutrino Facilities
Bhaskar Dutta, Debopam Goswami, Aparajitha Karthikeyan +1
Short-baseline neutrino (SBN) facilities are optimal for new-physics searches, including the possible production of new particles in and along the neutrino beamline. One such class…
