Thermal Resummation for Very Strong First-order Phase Transitions
Philipp Klose
Effective potentials are a key ingredient for predicting stochastic gravitational wave backgrounds from strong first-order phase transitions in the early universe. Established tech…
QCD corrections to the electroweak sphaleron rate
Dietrich Bödeker, Philipp Klose
The electroweak sphaleron rate in the high temperature phase of the Standard Model is inversely proportional to the weak-isospin conductivity. So far, only electroweak interactions…
Higher-dimensional operators at finite-temperature affect gravitational-wave predictions
Fabio Bernardo, Philipp Klose, Philipp Schicho +1
We investigate the effect of higher-dimensional marginal operators on the thermodynamics of cosmological phase transitions. Using the Abelian Higgs model as a representative for ra…
Upper Bound on Thermal Gravitational Wave Backgrounds from Hidden Sectors
Marco Drewes, Yannis Georis, Juraj Klaric +1
Hot viscous plasmas unavoidably emit a gravitational wave background, similar to electromagnetic black body radiation. We study the contribution from hidden particles to the diffus…
Gravitational wave background from vacuum and thermal fluctuations during axion-like inflation
P. Klose, M. Laine, S. Procacci
We revisit the framework of axion-like inflation in view of the possibility that the coupling of the inflaton to a non-Abelian topological charge density could lead to the generati…
Factorizing Hidden Particle Production Rates
Philipp Klose
A method is proposed to streamline the computation of hidden particle production rates by factorizing them into i) a model-independent SM contribution, and ii) a observable-indepen…
Gravitational wave background from non-Abelian reheating after axion-like inflation
P. Klose, M. Laine, S. Procacci
A pseudoscalar inflaton , coupled to the topological charge density of a non-Abelian sector, can decay to gauge bosons (), which may thermalize rapidly.…
Portal Effective Theories: A framework for the model independent description of light hidden sector interactions
Chiara Arina, Jan Hajer, Philipp Klose
We present a framework for the construction of portal effective theories (PETs) that couple effective field theories of the Standard Model (SM) to light hidden messenger fields. Us…
On Lepton Number Violation in Heavy Neutrino Decays at Colliders
Marco Drewes, Juraj Klarić, Philipp Klose
We study the perspective to observe lepton number violating signatures from heavy Majorana neutrino decays at colliders in view of the requirement to explain the light neutrino mas…
Relativistic and spectator effects in leptogenesis with heavy sterile neutrinos
Björn Garbrecht, Philipp Klose, Carlos Tamarit
For leptogenesis with heavy sterile neutrinos above the electroweak scale, asymmetries produced at early times (in the relativistic regime) are relevant, if they are protected from…
