3. Effective Field Theory for Thermal Phase transitions

Mikael Chala (Universidad de Granada)

30/01/2026, 11:00

I will present recent progress in applying effective field theory (EFT) to the precise computation of thermal phase transition parameters and the associated gravitational wave spectra. I will also briefly comment on byproducts of this work, including new methods for two-loop renormalization in EFT that avoid gauge-breaking counterterms and infrared rearrangement.

4. Baryogenesis from electroweak textures

Dr Simone Blasi (DESY)

27/02/2026, 10:00

The matter-antimatter asymmetry of the Universe represents one of the main open questions in particle physics and cosmology. In this talk, we will present a novel realization of cold baryogenesis (a mechanism involving the formation and decay of topological defects associated with the gauge group of the Standard Model known as SU(2) textures) that relies on the out-of-equilibrium dynamics...

12. Quantum Observables and Their Sensitivity to Fundamental Interactions at Polarized Lepton Colliders

Priyanka Lamba

27/02/2026, 11:30

High-energy colliders probe fundamental interactions through direct searches and precision measurements. Yet conventional observables, such as total cross sections and asymmetries do not fully exploit the intrinsically quantum nature of multi-particle final states. A density matrix based description of scattering processes provides access to genuinely quantum observables, offering...

11. Geometric resonances for high-frequency gravitational-wave detection

Jan Heisig

27/02/2026, 14:00

Gravitational waves at kilohertz and higher frequencies provide a unique window onto the early Universe at energy scales far beyond those accessible through the cosmic microwave background, potentially probing physics well above the electroweak scale. Yet existing detector concepts fall many orders of magnitude short of the big-bang nucleosynthesis bound on a stochastic gravitational-wave...

10. Bridging the microhertz gap in the gravitational-wave landscape

Alex Jenkins

27/02/2026, 15:20

Over the past decade, LIGO/Virgo/KAGRA have given us abundant evidence for gravitational waves emitted by binary systems. But binaries can also absorb gravitational waves, leaving potentially detectable imprints on their orbits. In this talk, I will describe how this effect can be used to search for gravitational waves at frequencies that are inaccessible to all other current and future...
