Gravitational Wave Echo of Relaxion Trapping
Abhishek Banerjee, Eric Madge, Gilad Perez +2
To solve the hierarchy problem, the relaxion must remain trapped in the correct minimum, even if the electroweak symmetry is restored after reheating. In this scenario, the relaxio…
Probing Higgs-portal dark matter with vector-boson fusion
Jan Heisig, Michael Krämer, Eric Madge +1
We constrain the Higgs-portal model employing the vector-boson fusion channel at the LHC. In particular, we include the phenomenologically interesting parameter region near the Hig…
Discovering the Decay in Associated Production
Florian Goertz, Eric Madge, Pedro Schwaller +1
We explore the prospects to discover the decay in -associated production, featuring a signal-to-background ratio of . Performing a detailed analys…
Dark, Cold, and Noisy: Constraining Secluded Hidden Sectors with Gravitational Waves
Moritz Breitbach, Joachim Kopp, Eric Madge +2
We explore gravitational wave signals arising from first-order phase transitions occurring in a secluded hidden sector, allowing for the possibility that the hidden sector may have…
Leptophilic dark matter from gauged lepton number: Phenomenology and gravitational wave signatures
Eric Madge, Pedro Schwaller
New gauge symmetries often appear in theories beyond the Standard Model. Here we study a model where lepton number is promoted to a gauge symmetry. Anomaly cancellation requires th…
