A Deep Dive into Baryon Asymmetry -- the C2HDM
Margarete Mühlleitner, Johann Plotnikov, Rui Santos +1
In this paper, we present our new implementation of the computation of the baryon asymmetry in the code BSMPT. It is based on the WKB ansatz generalizing the transport equations to…
Dark Matter in Multi-Singlet Extensions of the Standard Model
Maria Gonçalves, Margarete Mühlleitner, Rui Santos +1
We study the simplest extensions of the Standard Model (SM) that provide Dark Matter (DM) candidates, built with the addition of real singlets and new symmetries. I…
Reassessing CP Violation in the C2HDM with Machine Learning
Rafael Boto, Karim Elyaouti, Duarte Fontes +5
We provide a study of the parameter space of the complex 2-Higgs Doublet Model (C2HDM), focusing on signs of large CP-violating couplings of the 125 GeV Higgs boson with the fermio…
BSMPT v3 A Tool for Phase Transitions and Primordial Gravitational Waves in Extended Higgs Sectors
Philipp Basler, Lisa Biermann, Margarete Mühlleitner +3
Strong first-order phase transitions (SFOPT) during the evolution of the Higgs potential in the early universe not only allow for the dynamical generation of the observed matter-an…
