Speaker: Piotr Toczek (Warsaw University) Venue & Time: 15:00 / Red Room Abstract: Primordial black holes, hypothetical objects that may have formed in the early Universe through the interplay between high-energy physics and gravity, are very appealing candidates for dark matter. In this seminar, I will discuss their formation as a result of the collapse of […]
Alejandro Puga (IFT) will present "Particle Spectrum in Quantum Field Theory" de Alexander M. Polyakov (JETP Lett. 20 (1974) 194-195) Abstract: We investigate the nonperturbative structure of quantum field theories and its consequences for the physical spectrum of excitations. Emphasis is placed on the role of instantons—topologically nontrivial field configurations—which contribute essentially to tunneling processes and […]
Every Tuesday at 2:00 PM in the discussion room on the 5th floor. Join the IFT cosmology/gravity journal club at benty-fields.com to vote for papers and volunteer to present them.
Title: 'Probabilistic modeling and Bayesian inference for collider data' Speaker: Santiago Tanco (IFLP-CONICET/UNLP) Venue&Time: Gray Room 1 / 11:00
Madrid's Polygonal Gravity Seminar Series Wednesday, January 29th. Blue Room (IFT) 11:30h First talk Speaker: Robie Hennigar (U. Durham, UK) Title: Building Regular Black Holes Abstract: The study of regular (singularity-free) black holes has a long history, but progress has been limited by the absence of a dynamical framework in which they form and by […]
Strings, Pheno and the Swampland Journal Club Title: 'Mapping moduli across heterotic conifolds' Speaker: Christian Aoufia (IFT) Venue & Time: Red Room / 12:00 Abstract: In this work, we provide evidence for a duality between 4-dimensional Calabi-Yau compactifications of the heterotic string, in which the base manifolds are linked by a conifold transition. In recent […]
Title: 'GeV-scale QCD Axion' Speaker: Thomas Steingasser (IFT) Venue & Time: 12:00 / Gray Room 3 Abstract: In order to solve the strong CP problem, we study the possibility that the Peccei–Quinn symmetry is broken below the QCD scale. We find that a QCD axion can be above GeV, and may be among the observed […]
Title: 'Probing the Dark Sector with Large Scale Structure' Speaker: Ennio Salvioni (IFAE) Venue&Time: Red Room / 15:00 Abstract: Precision cosmology offers opportunities to test the nature of dark matter independently of any interactions with the visible sector. I will discuss how data from galaxy surveys, including the ongoing DESI and Euclid projects, can be […]
Gonzalo F. Casas (IFT) will present 'Topological Quantization and Cohomology' by Orlando Álvarez Commun.Math.Phys. 100 (1985) 279 Abstract: The relationships between topological charge quantization,Lagrangians and various cohomology theories are studied. A very general criterion for charge quantization is developed andapplied to various physical models. The relationship betweencohomology and homotopy is discussed.

Title: 'F(ℓ)avoured searches: new physics in the 3rd generation' Speaker: Tamara Vázquez Schröder (IFAE) Venue & Time: Red Room / 15:00 Abstract: The primary goal of the Large Hadron Collider (LHC) has been to discover the mechanism of electroweak symmetry breaking (EWSB). The discovery of the Standard Model (SM)-like Higgs boson in 2012 was the […]
