Electro-Weak Phase Transitions and Collider Signals in the Aligned 2-Higgs Doublet Model
Angela Conaci, Stefania De Curtis, Luigi Delle Rose +4
We show that the Aligned 2-Higgs Doublet Model (A2HDM) is a framework able to simultaneously accommodate strong first order electro-weak phase transitions, in turn generating detec…
Bubble wall velocity with out-of-equilibrium corrections
Carlo Branchina, Angela Conaci, Stefania De Curtis +1
We study how out-of-equilibrium effects modify the steady-state propagation of bubble walls during a cosmological first-order electroweak phase transition. Going beyond the local t…
Slaying Axion-Like Particles via Gravitational Waves and Primordial Black Holes from Supercooled Phase Transition
Angela Conaci, Luigi Delle Rose, P. S. Bhupal Dev +1
We study the formation of primordial black holes (PBHs) from density fluctuations due to supercooled phase transitions (PTs) triggered in an axion-like particle (ALP) model. We fin…
Electroweak Phase Transition and Bubble Wall Velocity in Local Thermal Equilibrium
Carlo Branchina, Angela Conaci, Stefania De Curtis +1
The dynamics of the electroweak phase transition in the early universe has profound implications for cosmology and particle physics. We systematically study the steady-state dynami…
New calculation of collision integrals for cosmological phase transitions
Carlo Branchina, Angela Conaci, Stefania De Curtis +4
First order phase transitions in the early universe may have left a variety of experimentally accessible imprints. The dynamics of such transitions is governed by the density pertu…
