SUMMARY:Pheno Journal Club: Unitarity limits on triple gauge boson production
DESCRIPTION:Daniel Domenech Moya (IFT) will present “Unitarity limits on triple gauge boson production”.\n\nVenue & Time: Gray Room 2 / 12:00\n\nAbstract:\n\nWe derive the unitarity constraints on anomalous quartic gauge couplings originating from the f ¯f ′ → V V ′V ′′ channel with V (′)(′′) = γ\, Z\, W ±\, and H. We also assess the importance of these bounds on the present and future experimental searches.

SUMMARY:Strings\, Pheno and the Swampland (SPS) Journal Club
DESCRIPTION:Every Thursday at 12:00 in the Red Room. \nTitulo: The Art of Branching: Cobordism Junctions of 10d String Theories \nSpeaker: Edoardo Anastasi (IFT) \nAbstract: We describe the explicit construction of configurations of several 10d string theories joining at a 9d junction\, providing a dynamical realization of cobordisms between multiple 10d string theories\, predicted by the Cobordism Conjecture. We provide the microscopic worldsheet description of the configuration in a generalization of the `going up and down the RG flow’ interpolations recently used in the description of IIA/IIB domain wall. The interpolations involve additional degrees of freedom\, which are gapped except at the branch point\, at which the gap closes and triggers the branching transition. The extra degrees of freedom admit an interpretation in terms of additional dimensions in a supercritical string theory\, which reduces to the 10d junction configuration upon closed tachyon condensation. Quantum corrections of the 2d worldsheet theory turn the junction into a strongly coupled lightlike core whose UV resolution lies beyond worldsheet techniques. We construct explicit examples of junctions of 10d heterotic string theories\, type 0\, and type II theories and orientifolds thereof. Our explicit examples include junctions of 10d chiral theories whose chiral fields flow between different branches. One particularly nice configuration is a 4-branch junction of the IIB theory\, with type I\, the non-supersymmetric USp(32) theory and the U(32) orientifold of 0B theory\, thus assembling the four non-tachyonic descendants of type 0B theory.

SUMMARY:Seminar: 'Symmetry TFTs for Continuous Spacetime Symmetries'
DESCRIPTION:Title: Symmetry TFTs for Continuous Spacetime Symmetries \nSpeaker: Iñaki Garcia Etxebarria (Durham U.) \nVenue & Time: Red Room / 3:00 PM \nAbstract: I will discuss our recent proposal for the Symmetry Topological Field Theory (SymTFT) for global\, continuous spacetime symmetries ( https://arxiv.org/abs/2509.07965 ). For a d-dimensional theory\, it is given by a (d + 1)-dimensional BF-theory for the spacetime symmetry group\, and whenever d is even\, it includes also Chern-Simons couplings\, that encode conformal and gravitational anomalies. This proposal is supported by the similarity to two- dimensional Jackiw-Teitelboim gravity in the d = 1 case and the topological limit of four-dimensional gravity in the d = 3 case. I will discuss how topological defects constructed from this SymTFT act by applying the associated spacetime symmetry transformation. Finally\, I will discuss the relation to gravity and holography.
