Every Thursday at 12:00 in the Red Room.
Mikel Martin (IFT) will present "Large scale perturbations in the open universe", by D. H. Lyth, & A. Woszczyna, Venue&Time: Blue Room / 17:00 Abstract: When considering perturbations in an open (Omega<1) universe, cosmologists retain only sub-curvature modes (defined as eigenfunctions of the Laplacian whose eigenvalue is less than -1 in units of the curvature […]
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 […]
Speaker: Pablo Viñas Martínez (IFT) Títle: 'Efficient Characterisation of Quantum Information Processors' Venue&Time: Gray Room 1 / 11:30 Abstract: "The precise characterisation and benchmarking of quantum information processors (QIPs) is essential for the development of quantum technologies. From the engineering of low-error physical components to the design of physically informed decoding strategies in quantum error […]
Speaker: José Garre Rubio Títle: 'Some Properties of Local One-Dimensional Hamiltonians' Venue&Time: Gray Room 1 / 11:30 Abstract: In this talk, I will discuss several properties of local Hamiltonians associated with the W state and matrix product states (MPS). I will begin by showing that the W state cannot be the unique ground state of […]
Speaker: Alberto Castellano (Chicago U.) Venue&Time: Red Room / 11:30
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 […]
