Clustering and Runaway Merging in a Primordial Black Hole Dominated Universe
Ian Holst, Gordan Krnjaic, Huangyu Xiao
If primordial black holes (PBH) are present in the early universe, their contribution to the energy budget grows relative to that of radiation and generically becomes dominant unle…
Observable CMB B-modes from Cosmological Phase Transitions
Kylar Greene, Aurora Ireland, Gordan Krnjaic +1
A B-mode polarization signal in the cosmic microwave background (CMB) is widely regarded as smoking gun evidence for gravitational waves produced during inflation. Here, we demonst…
The Affleck-Dine Curvaton
Aurora Ireland, Gordan Krnjaic, Takuya Okawa
The Standard Model of particle physics does not explain the origin of the universe's baryon asymmetry or its primordial fluctuations. The Affleck-Dine mechanism is a well-motivated…
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…
Warm Hawking Relics From Primordial Black Hole Domination
Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic
We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. I…
New Constraints on Axion-Like Particles with the NEON Detector at a Nuclear Reactor
Byung Ju Park, Jae Jin Choi, Eunju Jeon +17
We report new constraints on axion-like particles (ALPs) using data from the NEON experiment, which features a 16.7 kg of NaI(Tl) target located 23.7 meters from a 2.8 GW thermal p…
Hitting the Thermal Target for Leptophilic Dark Matter
Cari Cesarotti, Gordan Krnjaic
We study future lepton collider prospects for testing predictive models of leptophilic dark matter candidates with a thermal origin. We calculate experimental milestones for testin…
