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 non-standard neutrino interactions in Galactic supernovae

Bhaskar Dutta, Aparajitha Karthikeyan, Nityasa Mishra +2

We analyze the prospects for studying scalar non-standard interactions (SNSI) using the neutrino burst from a Galactic supernova. SNSI modify the resonant flavor conversion and, co…

`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…

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…
