Revisiting Critical Higgs Inflation: Electroweak Couplings, CMB Observables, and Perturbative Unitarity
Sarah R. Geller, Sol Gutierrez-Lara, David I. Kaiser +1
We revisit the scenario of critical Higgs inflation, in which inflation is driven by the Standard Model Higgs boson with parameters chosen close to a critical point, giving rise to…
Darkly Charged ALPs
Nicolás M. Arenaza, Enrique Fernández-Martínez, Belén Gavela +4
The established ALP effective Lagrangian describes the interaction of scalars with approximate shift-symmetry which carry no Standard Model (SM) charges with SM fields. It im…
Tunneling and tidal stripping in multifield ultralight dark matter halos
Benjamin V. Lehmann, Jackie Lodman, Thomas Steingasser
Tidal stripping is a key feature of the evolution of dark matter (DM) halos, and has major implications for the population of low-mass galaxies. In the case of ultralight DM, tidal…
On quantum tunnelling in the presence of Noether charges
Giulio Barni, Thomas Steingasser
We provide a complete first-principles based discussion of quantum tunnelling out of initial states carrying a conserved Noether charge. Our main result is a simple, unambiguous Eu…
