Status of Electroweak Baryogenesis in Minimal Composite Higgs
Sebastian Bruggisser, Benedict von Harling, Oleksii Matsedonskyi +1
We present an update on the status of electroweak baryogenesis in minimal composite Higgs models. The particularity of this framework is that the electroweak phase transition can p…
Dilaton at the LHC: Complementary Probe of Composite Higgs
Sebastian Bruggisser, Benedict von Harling, Oleksii Matsedonskyi +1
The dilaton is predicted in various extensions of the standard model containing sectors with an approximate spontaneously-broken conformal invariance. As a Goldstone boson of a spo…
Relaxion Dark Matter from Stochastic Misalignment
Aleksandr Chatrchyan, Géraldine Servant
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…
The Stochastic Relaxion
Aleksandr Chatrchyan, Géraldine Servant
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…
ALP Dark Matter Mini-Clusters from Kinetic Fragmentation
Cem Eröncel, Géraldine Servant
We show that very compact axion mini-clusters can form in models where axion-like-particle (ALP) dark matter is produced via the kinetic misalignment mechanism, which is well-motiv…
ALP Dark Matter from Kinetic Fragmentation: Opening up the Parameter Window
Cem Eröncel, Ryosuke Sato, Geraldine Servant +1
The main mechanism responsible for Axion-Like-Particle (ALP) production in the early universe is the so-called misalignment mechanism. Three regimes have been investigated in this…
