Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Carlo Branchina, Stefania De Curtis, Luigi Delle Rose +3
The paper investigates how thermal masses affect the friction on bubble walls during first-order cosmological phase transitions, showing that they suppress infrared gauge‑boson con…
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 $…
MuCol Milestone Report No. 7: Consolidated Parameters
Rebecca Taylor, Antoine Chancé, Dario Augusto Giove +459
This document is comprised of a collection of consolidated parameters for the key parts of the muon collider. These consolidated parameters follow on from the October 2024 Prelimin…
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…
The Muon Collider
Carlotta Accettura, Simon Adrian, Rohit Agarwal +450
Muons offer a unique opportunity to build a compact high-energy electroweak collider at the 10 TeV scale. A Muon Collider enables direct access to the underlying simplicity of the…
