Severe Constraints on New Physics Explanations of the MiniBooNE Excess
Johnathon R. Jordan, Yonatan Kahn, Gordan Krnjaic +2
The MiniBooNE experiment has recently reported an anomalous 4.5 excess of electron-like events consistent with appearance from a beam at short-baseline. Given the la…
Light Dark Matter eXperiment (LDMX)
Torsten Åkesson, Asher Berlin, Nikita Blinov +22
We present an initial design study for LDMX, the Light Dark Matter Experiment, a small-scale accelerator experiment having broad sensitivity to both direct dark matter and mediator…
WIMPflation
Dan Hooper, Gordan Krnjaic, Andrew J. Long +1
We propose a class of models in which a stable inflaton is produced as a thermal relic in the early universe and constitutes the dark matter. We show that inflaton annihilations ca…
Dark Matter, Millicharges, Axion and Scalar Particles, Gauge Bosons, and Other New Physics with LDMX
Asher Berlin, Nikita Blinov, Gordan Krnjaic +2
The proposed LDMX experiment would provide roughly a meter-long region of instrumented tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each elect…
Signatures of Pseudo-Dirac Dark Matter at High-Intensity Neutrino Experiments
Johnathon R. Jordan, Yonatan Kahn, Gordan Krnjaic +2
We (re)consider the sensitivity of past (LSND) and future (JSNS^2) beam dump neutrino experiments to two models of MeV-scale pseudo-Dirac dark matter. Both LSND and JSNS^2 are clos…
M: A New Muon Missing Momentum Experiment to Probe and Dark Matter at Fermilab
Yonatan Kahn, Gordan Krnjaic, Nhan Tran +1
New light, weakly-coupled particles are commonly invoked to address the persistent anomaly in and serve as mediators between dark and visible matter. If such pa…
Severely Constraining Dark Matter Interpretations of the 21-cm Anomaly
Asher Berlin, Dan Hooper, Gordan Krnjaic +1
The EDGES Collaboration has recently reported the detection of a stronger-than-expected absorption feature in the global 21-cm spectrum, centered at a frequency corresponding to a…
Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab: an update on PR12-16-001
M. Battaglieri, A. Bersani, G. Bracco +123
This document is an update to the proposal PR12-16-001 Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab submitted to JLab-PAC44 in 2016 reporting progress in add…
