Title: 'First Order Phase Transitions and Gravitational Waves' Venue&Time: Red Room / 15:00 Speaker: Marco Finetti (U. Aveiro) Abstract: The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave (GW) detector, opening a new observational window for both astrophysics and early-Universe cosmology. Operating in the millihertz band, it will probe a rich […]
Title: 'Classical Krylov probes and chaotic semiclassical strings' Speaker: Saskia Demulder (CUNEF) Venue&Time: Red Room / 15:00 Abstract: Quantum chaos is a central theme in string theory, but classical chaos is also a generic feature of semiclassical string dynamics. Motivated by the need to explore the broad landscape of non-integrable string dynamics, I will introduce […]
Title: ‘A diffuse flux of MeV ALPs’ Speaker: Marina Cermeño Venue&Time: Red Room / 15:00 Abstract: MeV scale axion-like particles can be produced with semi-relativistic velocities in Galactic supernovae, leading to a diffuse flux that can be detectable in neutrino water-Cherenkov detectors (Super + HyperK). In this talk, I will explain the details of the […]
Title: Revisiting Critical Higgs Inflation: CMB Observables, Electroweak Couplings, and Perturbative Unitarity Speaker: Sarah R. Geller (Yale U.) Venue & Time: Red Room / 15:00 Abstract: An intriguing and economical possibility to explain many cosmological observations is Higgs inflation, in which inflation is driven by the Standard Model Higgs with a non-minimal coupling to gravity. I […]
Every Thursday at 12:00 in the Red Room.
Title: 'A hot take on electroweak skyrmions' Speaker: Luis Gil (Universidad de Granada). Venue&Time: Red Room / 15:00 Abstract: Skyrmions are stable and topologically non-trivial field configurations that behave like localized particles. They appear in the chiral effective theory for pions, where they correspond to the baryon states, and might also exist in the electroweak […]
Title: 'Differential observables for the Higgs-strahlung process to all orders in EFT.' Speaker: Sourav Bera from Tata Institute of Fundamental Research (TIFR) Venue&Time: Red Room / 15:00 Abstract: We develop methods to obtain the fully differential cross-section for the f f \to Z(ll) h process to any desired order in effective field theory (EFT). To […]
Title: 'NLO Running in the SMEFT' Speaker: Lukas Born (University of Bern). Venue&Time: Red Room / 15:00 Abstract: The Standard Model Effective Field Theory (SMEFT) provides a systematic framework for parameterizing heavy new physics in a model-independent way. A central ingredient for precision analyses within this framework is the renormalization group equations (RGEs), governing the […]
Title: 'Sub-GeV Dark Matter, Neutrino Masses, and Astrophysical Signals from a Rich Dark Sector.' Speaker: Elina Merkel (University of Bologna) Venue&Time: Red Room / 15:00 Abstract: Rich dark sectors provide an attractive framework for addressing several puzzles in particle physics and cosmology within a single model. In this talk, I will present a simple sub-GeV […]
Title: ‘The Hunt for Multiple Axions’ Speaker: Arturo de Giorgi (University of Durham). Venue&Time: Red Room / 15:00 Abstract: Axions and axion-like particles may arise in Nature as a spectrum rather than as a single field. Such a scenario naturally emerges in string-inspired constructions, as well as in reasonably simple bottom-up extensions of single axion […]
