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…
