Cancellation of divergences up to three loops in exceptional field theory
Guillaume Bossard, Axel Kleinschmidt
We consider the tetrahedral three-loop diagram in exceptional field theory evaluated as a scalar diagram for four external gravitons. At lowest order in momenta, this diagram…
Two Kissing Bolts
Guillaume Bossard, Stefanos Katmadas, David Turton
The study of non-supersymmetric black hole microstates offers the potential to resolve the black hole information paradox. A system of equations was recently obtained that enables…
Generalised diffeomorphisms for E
Guillaume Bossard, Martin Cederwall, Axel Kleinschmidt +2
We construct generalised diffeomorphisms for E exceptional field theory. The transformations, which like in the E case contain constrained local transformations, close when…
Beyond E11
Guillaume Bossard, Axel Kleinschmidt, Jakob Palmkvist +2
We study the non-linear realisation of E11 originally proposed by West with particular emphasis on the issue of linearised gauge invariance. Our analysis shows even at low levels t…
Four-derivative couplings and BPS dyons in heterotic CHL orbifolds
Guillaume Bossard, Charles Cosnier-Horeau, Boris Pioline
Three-dimensional string models with half-maximal supersymmetry are believed to be invariant under a large U-duality group which unifies the S and T dualities in four dimensions. W…
