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…
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…
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…
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…
