Baryon Asymmetry from Electroweak-Symmetric Domain Walls
Jacopo Azzola, Oleksii Matsedonskyi, Andreas Weiler
We investigate electroweak baryogenesis from domain walls with electroweak-symmetric cores moving through the electroweak-broken plasma. In the thick-wall regime, CP-violating semi…
Inverse Electroweak Baryogenesis
Jacopo Azzola, Oleksii Matsedonskyi, Andreas Weiler
We propose a mechanism for baryogenesis in which the baryon asymmetry is generated as an equilibrium response of weak sphalerons in a region where electroweak sphaleron transitions…
-Dwarfs: White Dwarfs probe Quadratically Coupled Scalars
Kai Bartnick, Konstantin Springmann, Stefan Stelzl +1
We study ultralight scalar fields with quadratic couplings to Standard-Model fermions and derive strong constraints from white-dwarf mass-radius data. Such couplings source scalar…
A Universal Bound on QCD Axions from Supernovae
Konstantin Springmann, Michael Stadlbauer, Stefan Stelzl +1
We identify a new production channel for QCD axions in supernova environments that contributes to axion emissivity for all models solving the strong CP problem. This channel arises…
From Supernovae to Neutron Stars: A Systematic Approach to Axion Production at Finite Density
Konstantin Springmann, Michael Stadlbauer, Stefan Stelzl +1
We present a systematic study of QCD axion production in environments with finite baryon density and temperature, implying significant changes to axion phenomenology. Within heavy…
Quantum collider probes of the fermionic Higgs portal
U. Haisch, M. Ruhdorfer, K. Schmid +1
We explore the sensitivity of future hadron colliders to constrain the fermionic Higgs portal, with a focus on scenarios where the new fermions cannot be directly observed in exoti…
