Massive vector fields in Kerr--Newman and Kerr--Sen black hole spacetimes

Ramiro Cayuso, Oscar J. C. Dias, Finnian Gray +5

The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein--Maxwell gravity (the Kerr--Newman solution)…

The O(N) S-matrix Monolith

Lucía Córdova, Yifei He, Martin Kruczenski +1

We consider the scattering matrices of massive quantum field theories with no bound states and a global symmetry in two spacetime dimensions. In particular we explore the sp…

SUSY S-matrix Bootstrap and Friends

Carlos Bercini, Matheus Fabri, Alexandre Homrich +1

We consider the 2D S-matrix bootstrap in the presence of supersymmetry, and symmetry. At the boundary of the allowed S-matrix space we encounter well…

Approximate Symmetries and Gravity

Sylvain Fichet, Prashant Saraswat

There are strong reasons to believe that global symmetries of quantum theories cannot be exact in the presence of gravity. While this has been argued at the qualitative level, esta…

Principal Tensor Strikes Again: Separability of Vector Equations with Torsion

Ramiro Cayuso, Finnian Gray, David Kubiznak +3

Many black hole spacetimes with a 3-form field exhibit a hidden symmetry encoded in a torsion generalization of the principal Killing--Yano tensor. This tensor determines basic pro…

Flux Tube S-matrix Bootstrap

Joan Elias Miro, Andrea L. Guerrieri, Aditya Hebbar +2

We bootstrap the S-matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S-matrices is strongl…

Notes on Biadjoint Amplitudes, and Scattering Equations

Freddy Cachazo, Jairo M. Rojas

In these notes we use the recently found relation between facets of tropical Grassmannians and generalizations of Feynman diagrams to compute all "biadjoint amplitudes" for a…

Five-Point Function from Supergravity

Vasco Gonçalves, Raul Pereira, Xinan Zhou

We develop new techniques to compute five-point correlation functions from IIB supergravity on . Our methods rely entirely on symmetry and general consistency cond…

The S-matrix Bootstrap IV: Multiple Amplitudes

Alexandre Homrich, Joao Penedones, Jonathan Toledo +2

We explore the space of consistent three-particle couplings in -symmetric two-dimensional QFTs using two first-principles approaches. Our first approach relies solely…

Opacity and Effective Field Theory in Anti-de Sitter Backgrounds

Sylvain Fichet

We consider quantum field theory in a five-dimensional anti-de Sitter background, possibly truncated by 4d branes. In the Euclidian version of this space, it is known that propagat…

Half-BPS Vertex Operators of the Superstring

Nathan Berkovits

Using the pure spinor formalism for the superstring in an background, a simple expression is found for half-BPS vertex operators. At large radius, these vertex op…

Octagons I: Combinatorics and Non-Planar Resummations

Till Bargheer, Frank Coronado, Pedro Vieira

We explain how the 't Hooft expansion of correlators of half-BPS operators can be resummed in a large-charge limit in N=4 super Yang-Mills theory. The full correlator in the limit…

On the Spectrum and Spacetime Supersymmetry of Heterotic Ambitwistor String

Henrique Flores, Matheus Lize

We analyse the BRST cohomology of the Ramond sector of heterotic ambitwistor theory. We also write the free string field theory action and compute the supersymmetry transformations…
