A Comprehensive Analysis of the R2HDM Vacuum Evolution and the Induced GW and Collider Phenomenology
Lisa Biermann, Christoph Borschensky, Rafael Boto +3
Extended Higgs sectors beyond the Standard Model (BSM) allow to dynamically generate the observed baryon asymmetry of the Universe through electroweak baryogenesis and thereby solv…
Polyakov Loops Tame Phase Transitions
Lisa Biermann, Joydeep Chakrabortty, Christoph Englert
We estimate the impact of Polyakov loop (PL) contributions on electroweak phase transitions (PTs). We show that the PL, which is unavoidable in thermal gauge field theory, tends to…
Phenomenology of a Kinetic Higgs Portal
Anisha, Lisa Biermann, Christoph Englert +1
We explore the phenomenological consequences of non-minimal hidden sector interactions on observable correlations in the Higgs sector, mediated through the -symmetric…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
Double and Triple Higgs Production to probe the Electroweak Phase Transition
Lisa Biermann, Christoph Borschensky, Christoph Englert +2
The production of three Higgs bosons could be a stretch goal for the LHC and a strategic case for future colliders. In this work, we analyse the phenomenological prospects of (neut…
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…
Effective 2HDM Yukawa Interactions and a Strong First-Order Electroweak Phase Transition
Anisha, Duarte Azevedo, Lisa Biermann +2
The top quark as the heaviest particle in the Standard Model (SM) defines an important mass scale for Higgs physics and the electroweak scale itself. It is therefore a well-motivat…
Intermediate Charge-Breaking Phases and Symmetry Non-Restoration in the 2-Higgs-Doublet Model
Mayumi Aoki, Lisa Biermann, Christoph Borschensky +3
The Higgs potentials of extended Higgs sectors exhibit a complex and interesting vacuum structure. When travelling back in time, i.e. going to higher temperatures, the structure ma…
`CP in the Dark' and a Strong First-Order Electroweak Phase Transition
Lisa Biermann, Margarete Mühlleitner, Jonas Müller
We investigate the potential of the model `CP in the Dark' for providing a strong first-order electroweak phase transition (SFOEWPT) by taking into account all relevant theoretical…
Electroweak Phase Transition in a Dark Sector with CP Violation
Lisa Biermann, Margarete Mühlleitner, Jonas Müller
In this paper, we investigate the possibility of a strong first-order electroweak phase transition (SFOEWPT) in the model `CP in the Dark'. The Higgs sector of the model consists o…
Two Higgs doublets, Effective Interactions and a Strong First-Order Electroweak Phase Transition
Anisha, Lisa Biermann, Christoph Englert +1
It is well-known that type II two Higgs doublet models (2HDMs) can struggle to facilitate a strong first-order electroweak phase transition in the early universe whilst remaining t…
Electroweak Baryogenesis in the CP-Violating Two-Higgs Doublet Model
Philipp Basler, Margarete Mühlleitner, Jonas Müller
Recently we presented the upgrade of our code BSMPT for the calculation of the electroweak phase transition (EWPT) to BSMPT v2 which now includes the computation of the baryon asym…
