Description

Baryon asymmetry problem is one of the most discussed question of the cosmology. Composite Higgs model suggests one of the possible the approaches to the problem within electroweak phase transition. However, the required first order phase is hardly described within perturbative methods. AdS/CFT provides non-perturbative approach to this problem. We estimated the parameters of the first order phase transition in the bottom-up holographic composite Higgs model and the gravitational wave spectrum produced during the bubble nucleation. We consider string top-down models to generalize our approach to the problem.
