The Stochastic Relaxion

Autor: Chatrchyan, Aleksandr, Servant, Geraldine

Publikováno v: Journal of High Energy Physics

We revisit the original proposal of cosmological relaxation of the electroweak scale by Graham, Kaplan and Rajendran in which the Higgs mass is scanned during inflation by an axion field, the relaxion. We investigate the regime where the relaxion is

Relaxion Dark Matter from Stochastic Misalignment

Autor: Chatrchyan, Aleksandr, Servant, Geraldine

Cosmological relaxation of the electroweak scale via Higgs-axion interplay, named as relaxion mechanism, provides a dynamical solution to the Higgs mass hierarchy. In the original proposal by Graham, Kaplan and Rajendran, the relaxion abundance today

Electroweak Asymmetric Early Universe via a Scalar Condensate

Autor: Chang, Jae Hyeok, Olea Romacho, Maria Olalla, Tanin, Erwin H.

Finite temperature effects in the Standard Model tend to restore the electroweak symmetry in the early universe, but new fields coupled to the higgs field may as well reverse this tendency, leading to the so-called electroweak symmetry non-restoratio
