Seminars

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 […]

Title: 'Asymmetric Dark Matter induced by Baryogenesis' Speaker: Miguel Escudero (CERN) Venue&Time: Red Room / 15:00 Abstract: We live in a Universe where structures are made out of baryons but not of antibaryons. Could the dark matter be made of particles and not antiparticles? This is an old question and many asymmetric dark matter scenarios […]

Speaker: Shunsuke Neda (ICRR, Univ. of Tokyo) Venue & Time: Red Room / 15:00 Title: Primordial black holes from Q-balls Abstract:  We discuss primordial black holes (PBHs) originating from Q-balls, which are non-topological solitons arising in complex scalar field theories with a global U(1) symmetry. Depending on the cosmic expansion history, Q-balls can source PBH formation in […]

Gravity, Supergravity and Superstrings (GRASS) Seminar Speaker: David Pereñiguez (Johns Hopkins U.) Title: 'Gravitational Duality at the Lightring, QNM isospectrality, and Ringdown Nonlinearities from Penrose Limits' Abstract: At high frequencies, the physics near a black hole’s lightring can be captured by Penrose-limit plane waves adapted to the photon sphere. In this talk, I will solve […]

Title: 'Sub-PeV gamma-ray astronomy and its physics' Speaker: Sei Kato (Sorbonne Université, Institut d'Astrophysique de Paris) Venue&Time: Red Room / 15:00 Abstract: This talk will focus on the physics that can be explored with sub-PeV gamma-ray astronomy (E > 10^14 eV), particularly on the Galactic diffuse gamma rays and the dark matter. Also, our project […]

Title: 'The tensions of LCDM: An update of observations and theoretical implications' Speaker: Leandros Perivolaropoulos (Ioannina) Venue&Time: Red Room / 15:00 Abstract: The standard LCDM cosmological model, despite its success in describing the large-scale structure of the Universe, is currently challenged by statistically significant discrepancies between early and late-universe observations. In this talk, I provide […]
