Journal ArticleDOI
Relaxation from particle production
TL;DR: In this article, the authors use particle production as a friction force by which to implement a relaxation solution to the electroweak hierarchy problem, which avoids superplanckian field excursions and avoids any conflict with the strong CP problem.
Journal ArticleDOI
Opening up the QCD axion window
TL;DR: In this paper, the axion couples to a massless dark photon with a coupling that is moderately stronger than axion coupling to gluons, making decay constants as high as fa ≃ 1017 GeV viable for generic initial conditions.
Journal ArticleDOI
A collider observable QCD axion
TL;DR: In this paper, a model where the QCD axion is at the TeV scale and visible at a collider via its decays is presented, which predicts additional pseudoscalar color octets whose properties are completely determined by the axion properties.
Journal ArticleDOI
Interacting radiation after Planck and its implications for the Hubble Tension
TL;DR: In this paper, the authors consider several extensions of the standard cosmology that include a non-free-streaming radiation component as motivated by such particle physics models and use the final Planck data release to constrain them.
Journal ArticleDOI

TL;DR: In this paper, it was shown that even at couplings where too few dark photons are produced in supernovae to violate the cooling bound, they can be observed directly through their decays.
