Can QCD Axions Survive the Cosmological Constant Problem?
Carsten van de Bruck, C. P. Burgess, Adam Smith
Mechanisms that dynamically relax the vacuum energy offer a concrete way to approach the cosmological constant problem, but because relaxation is not confined to the vacuum energy…
The Serendipitous Axiodilaton: A Self-Consistent Recombination-Era Solution to the Hubble Tension
Adam Smith, Maria Mylova, Carsten van de Bruck +2
Axio-dilaton cosmology provides a minimal benchmark model for both Dark Matter (DM) and Dark Energy (DE) that is well motivated by fundamental physics. The axion and dilaton arise…
Shape of Dark Energy: Constraining Its Evolution with a General Parametrization
Dong Ha Lee, Weiqiang Yang, Eleonora Di Valentino +2
We consider a general dark energy (DE) model parametrized by its equation-of-state (EoS), featuring three free parameters: (the present-day value of the DE EoS), (quant…
A low-redshift preference for an interacting dark energy model
Yuejia Zhai, Marco de Cesare, Carsten van de Bruck +2
We explore an interacting dark sector model in trace-free Einstein gravity where dark energy has a constant equation of state, , and the energy-momentum transfer potential is…
Alleviating cosmological tensions with a hybrid dark sector
Elsa M. Teixeira, Gaspard Poulot, Carsten van de Bruck +2
We investigate a cosmological model inspired by hybrid inflation, where two scalar fields representing dark energy (DE) and dark matter (DM) interact through a coupling that is pro…
A Minimal Axio-dilaton Dark Sector
Adam Smith, Maria Mylova, Philippe Brax +3
In scalar-tensor theories it is the two-derivative sigma-model interactions that like to compete at low energies with the two-derivative interactions of General Relativity (GR) $\u…
