Seminars

Speaker: Suraj Prakash, IFIC (Valencia) Venue&Time: Red Room / 3:00 PM Abstract: The talk will present a study of the sensitivity of COHERENT-like experiments to non-standard neutrino interactions within the vWEFT framework, i.e. low-energy EFT with additional right-handed Dirac neutrinos. Our analysis incorporates, for the first time, flavor-general New Physics effects in both neutrino production […]

Speaker: Daniel González Cuadra (IFT) Venue&Time: Red Room / 15:00 Abstract: Lattice gauge theories (LGTs) describe a broad range of phenomena in condensed matter and particle physics. A prominent example is confinement, responsible for bounding quarks inside hadrons such as protons or neutrons. When quark-antiquark pairs are separated, the energy stored in the string of […]

GRASS (GRAvity, Supergravity & Superstrings) Seminar Speaker: Cristóbal Andrés Corral (Universidad Adolfo Ibáñez, Chle) Venue & Time: Red Room / 15:00 Abstract: We discuss the (anti-)self-duality conditions under which the electric and magnetic parts of the conserved charges of the dyonic Kerr-Newman-NUT-AdS solution become equivalent. Within a holographic framework, the stress tensor and the boundary […]

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 […]
