 Cyclic spacetimes through singularity scattering maps. Plane-symmetric gravitational collisions / Floch, Bruno Le ; LeFloch, Philippe G. ; Veneziano, Gabriele We study the plane-symmetric collision of two gravitational waves and describe the global spacetime geometry generated by this collision.

 Higher-Form Symmetries and their Anomalies in M-/F-theory Duality / Cvetic, Mirjam ; Dierigl, Markus (Munich U., ASC) ; Lin, Ling (CERN) ; Zhang, Hao Y. (Pennsylvania U.) We explore higher-form symmetries of M- and F-theory compactified on elliptic fibrations, determined by the topology of their asymptotic boundaries.

 Discriminating same-mass Neutron Stars and Black Holes gravitational wave-forms / Coupechoux, J.-F. (IP2I, Lyon) ; Arbey, A. ; Chierici, R. (IP2I, Lyon) ; Hansen, H. (IP2I, Lyon) ; Margueron, J. (IP2I, Lyon) ; Sordini, V. (IP2I, Lyon) Gravitational wave-forms from coalescences of binary black hole systems and binary neutron star systems with low tidal effects can hardly be distinguished if the two systems have similar masses.

 SMEFT Constraints on New Physics Beyond the Standard Model / Ellis, John (King's Coll. London ; NICPB, Tallinn ; CERN) The Fermi effective theory of the weak interaction helped identify the structure of the electroweak sector of the Standard Model, and the chiral effective Lagrangian pointed towards QCD as the theory of the strong interactions.
