Resonant Di-Higgs Searches in at HL-LHC: Supersymmetry versus Compositeness Benchmarks
Atri Dey, Carl Johan Konigsson, Stefano Moretti +3
We explore the scope of the High-Luminosity Large Hadron Collider (HL-LHC) in testing Standard Model (SM) di-Higgs production and decay into final states in the context of t…
Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Carlo Branchina, Stefania De Curtis, Luigi Delle Rose +3
Bubble-wall friction controls the dynamics of first-order cosmological phase transitions. In Boltzmann-equation approaches, a major uncertainty arises from infrared gauge bosons, w…
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…
Searches for Extra Higgs Bosons using Higgs{} Events within 2HDMs: Direct versus Indirect Probes
Esteban Chalbaud, Stefania De Curtis, Luigi Delle Rose +3
We study the possibility of establishing the production of additional Higgs states in the process , where = , with being CP-even and $H_…
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…
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…
