Seminars

Speaker: Gonzalo Herrera (MIT & Harvard) Venue & Time: Red Room / 15:00 Abstract: The vicinity of supermassive black holes at the center of Galaxies represents one of the most extreme environments in the Universe. In Active Galactic Nuclei (AGN), intense gravitational fields, relativistic particle acceleration, strong magnetic fields, and dense ambient gas and radiation coexist in conditions […]

Gravity, Supergravity and Superstrings (GRASS) Seminar Speaker: Ziqi Yan (Niels Bohr Institute, Denmark) Venue & Time: Red Room / 15:00 Abstract: Scalar fields with masses protected by global shift symmetries, commonly referred to as axions, are abundantly used in effective field theories in cosmology and particle physics. I will discuss a (4+1) dimensional braneworld construction […]

Speaker: Cristina Puchades Ibáñez (University of Mainz) Venue & Time: Red Room / 15:00 Abstract: We explore the dynamics of cosmological phase transitions in a dark sector model featuring a dark photon associated with a U(1)D gauge symmetry and radiative symmetry breaking. Our analysis focuses on different approaches to construct the effective potential: the high-temperature […]

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 […]

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 […]

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 […]

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 […]

Speaker: Tom Rudelius (Durham U., Dept. of Math.) Title: Co-Scaling and Alignment of Electric and Magnetic States Venue & Time: Red Room / 11:30 Abstract: Towers of electrically and magnetically charged states in quantum gravity often exhibit two important properties. First, the ratio of the mass (or tension) of electrically charged states to magnetically charged […]

Title: 'UV completion of extended Higgs models via the confinement of SU(2) gauge' Speaker: Yushi Mura (KEK) Venue & Time: Red Room / 15:00 Abstract: The extended Higgs sectors are often introduced to explain phenomena beyond the standard model. On the other hand, the existence of multiple scalar fields may cause the Landau pole below […]

Speaker: Zoltan Fodor (Penn State U.) Venue & Time: Red Room / 15:00 Title: The Muon Magnetic Moment Mystery: a 20-year puzzle in high-energy physics Abstract: In the last two decades or so there have been stronger and stronger disagreements between direct measurements of the anomalous magnetic moment of the muon and the standard-model prediction. Such a […]
