Probing the Cosmic Axion Background via Axion-Photon Conversion in Filaments
Duncan Rocha, Gordan Krnjaic, Matthew J. Baldwin
The cosmic axion background (CaB) is a hypothetical population of relativistic axions produced in the early universe. If the CaB is produced from dark matter decays, the axions in…
Primordial Neutron Stars
Gordan Krnjaic, Duncan Rocha, Huangyu Xiao
We propose a novel cosmological scenario in which baryonic neutron stars could plausibly form in the early universe. If baryogenesis initially produces an excessively-large baryon…
The Price of a Large Electron Yukawa Modification
Lukas Allwicher, Matthew McCullough, Sophie Renner +2
The theoretical implications of an electron Yukawa modification are considered in the context of a possible Higgs pole run at FCC-ee, aimed at bounding this coupling. We start from…
Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter
Dan Hooper, Gordan Krnjaic, Duncan Rocha +1
We explore a simple and predictive dark matter scenario involving a complex scalar field, , coupled to the Higgs portal with no additional field content. In the UV, the field po…
Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC
Ernesto Arganda, Marcela Carena, Martín de los Rios +4
The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning…
Discovering Dark Matter with the MUonE Experiment
Gordan Krnjaic, Duncan Rocha, Isaac R. Wang
The MUonE experiment aims to extract the hadronic contribution to the muon anomalous magnetic moment from a precise measurement of the muon-electron differential scattering cross s…
The Non-Relativistic Effective Field Theory Of Dark Matter-Electron Interactions
Gordan Krnjaic, Duncan Rocha, Tanner Trickle
Electronic excitations in atomic, molecular, and crystal targets are at the forefront of the ongoing search for light, sub-GeV dark matter (DM). In many light DM-electron interacti…
New Forces From Sources
Cari Cesarotti, Yonatan Kahn, Gordan Krnjaic +2
Accelerator-based experiments reliant on charged pion and kaon decays to produce muon-neutrino beams also deliver an associated powerful flux of muons. Therefore, these experiments…
