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…
High-Energy Nuclear Recoils from Boosted Dark Matter for the LZ 248-keV Event: Beyond the Halo-Dependent High-Velocity Tail
Haider Alhazmi, Doojin Kim, Kyoungchul Kong +2
The LUX-ZEPLIN (LZ) Collaboration has reported a nuclear-recoil candidate at keV, with a maximum local significance of and a global…
Primordial Black Hole Hotspots Beyond Flat Spacetime
Doojin Kim, TaeHun Kim, Jong-Chul Park +1
Light primordial black holes heat the surrounding plasma via Hawking radiation, forming localized hotspots whose temperature may far exceed that of the cosmological background. Pre…
The DAMSA Experiment
Prithak Bhattarai, Andrew Brandt, Alan Bross +41
DAMSA (DArk Messenger Searches at an Accelerator) is a novel short-baseline accelerator/beam dump experiment aimed at probing short-lived physics processes, including searches for…
Analytical and Machine Learning Methods for Model Discernment at CENS Experiments
Iain A. Bisset, Bhaskar Dutta, Doojin Kim +2
Neutrino experiments are often limited by low statistics, sizable systematic uncertainties, and coarse observable binning, which can hinder discrimination among competing beyond-th…
DAMSA Experiment Conceptual Design White Paper
Prithak Bhattarai, Andrew Brandt, Alan Bross +41
DAMSA (DArk Messenger Searches at an Accelerator) is a novel short-baseline accelerator experiment aimed at probing short-lived physics processes, including searches for evidence o…
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…
Finding BSM Needles in Electromagnetic Haystacks at DUNE
Vedran Brdar, Bhaskar Dutta, Wooyoung Jang +5
In this work, motivated by several beyond the Standard Model signal topologies, we perform detailed background mitigation analyses for the DUNE near detector. Specifically, we inve…
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…
Direct Detection of Fast-Moving Low-Mass Dark Matter
Haider Alhazmi, Doojin Kim, Kyoungchul Kong +3
We examine the signals produced by dark matter interactions with electrons, which play a crucial role in direct detection experiments employing heavy target materials, particularly…
Prospects for Light Dark Matter Searches at Large-Volume Neutrino Detectors
Bhaskar Dutta, Wei-Chih Huang, Doojin Kim +3
We propose a new approach to search for light dark matter (DM), with keV-GeV mass, via inelastic nucleus scattering at large-volume neutrino detectors such as Borexino, DUNE, Super…
Beam-Dump Ceiling and Its Experimental Implication: The Case of a Portable Experiment
Doojin Kim, Jaehoon Yu, Jong-Chul Park +1
We generalize the nature of the so-called beam-dump ``ceiling'' beyond which the improvement on the sensitivity reach in the search for fast-decaying mediators dramatically slows d…
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…
