Probing Heavy Neutral Leptons through New Gauge Interactions at the Forward Physics Facilities
Francis M. Burk, P. S. Bhupal Dev, Bhaskar Dutta +3
We investigate the prospects for improving the heavy neutral lepton (HNL) searches at the far-forward LHC experiments FASER and FASER, as well as their proposed HL-LHC successor…
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…
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…
Scalar nonstandard neutrino interactions in galactic supernovae
Bhaskar Dutta, Aparajitha Karthikeyan, Nityasa Mishra +2
We analyze the prospects for studying scalar nonstandard interactions (SNSI) using the neutrino burst from a galactic supernova (SN). SNSI modifies the resonant flavor conversion a…
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 Standar…
`Dark' Matter Effect as a Novel Solution to the KM3-230213A Puzzle
P. S. Bhupal Dev, Bhaskar Dutta, Aparajitha Karthikeyan +3
The recent KM3NeT observation of an event KM3-230213A is puzzling because IceCube with much larger effective area times exposure has not found any such e…
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 astrop…
Photon Excess from Dark Matter and Neutrino Scattering at MiniBooNE and MicroBooNE
Bhaskar Dutta, Aparajitha Karthikeyan, Doojin Kim +2
We propose new solutions to accommodate both the MiniBooNE electron-like and MicroBooNE photon low-energy excesses, based on interactions involving light dark matter and/or neutrin…
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…
Dark Matter Internal Pair Production -- A Novel Direct Detection Mechanism
Bhaskar Dutta, Aparajitha Karthikeyan, Hyunyong Kim +1
We propose a novel mechanism, dark matter internal pair production (DIPP), to detect dark matter candidates at beam dump facilities. When energetic dark matter scatters in a materi…
