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…
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…
