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…
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…
UV-Complete Models for a Light Axial Gauge Boson
Bhaskar Dutta, Aparajitha Karthikeyan, Rabindra N. Mohapatra
We present new anomaly free gauge models where the gauge field only has axial vector couplings to both quarks and leptons. We use the left-right symmetric universal seesaw models a…
Time-Varying Reach-Avoid Control Certificates for Stochastic Systems
Rayan Mazouz, Luca Laurenti, Morteza Lahijanian
Reach-avoid analysis is fundamental to reasoning about the safety and goal-reaching behavior of dynamical systems, and serves as a foundation for specifying and verifying more comp…
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…
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…
New Physics at Neutron Beam Dump
P. S. Bhupal Dev, Bhaskar Dutta, Tao Han +3
We find a new utility of neutrons, usually treated as an experimental nuisance causing unwanted background, in probing new physics signals. They can either be radiated from neutron…
Longer-Lived Mediators from Charged Mesons and Photons at Neutrino Experiments
Bhaskar Dutta, Aparajitha Karthikeyan, Doojin Kim
Since many of the dark-sector particles interact with Standard Model (SM) particles in multiple ways, they can appear in experimental facilities where SM particles appear in abunda…
PIP2-BD: GeV Proton Beam Dump at Fermilab's PIP-II Linac
M. Toups, R. G. Van de Water, Brian Batell +27
The PIP-II superconducting RF linac is currently under construction at Fermilab and is expected to be completed by the end of 2028. PIP-II is capable of operating in a continuous-w…
