A fusion for the periodic Temperley-Lieb algebra and its continuum limit

Azat M. Gainutdinov, Jesper L. Jacobsen, Hubert Saleur

The equivalent of fusion in boundary conformal field theory (CFT) can be realized quite simply in the context of lattice models by essentially glueing two open spin chains. This ha…

Asymptotically-flat supergravity solutions deep inside the black-hole regime

Iosif Bena, Stefano Giusto, Emil J. Martinec +4

We construct an infinite family of smooth asymptotically-flat supergravity solutions that have the same charges and angular momenta as general supersymmetric D1-D5-P black holes, b…

Higher Spin de Sitter Hilbert Space

Dionysios Anninos, Frederik Denef, Ruben Monten +1

We propose a complete microscopic definition of the Hilbert space of minimal higher spin de Sitter quantum gravity and its Hartle-Hawking vacuum state. The fundamental degrees of f…

Beyond Amplitudes' Positivity and the Fate of Massive Gravity

Brando Bellazzini, Francesco Riva, Javi Serra +1

We constrain effective field theories by going beyond the familiar positivity bounds that follow from unitarity, analyticity, and crossing symmetry of the scattering amplitudes. As…

Renormalised 3-point functions of stress tensors and conserved currents in CFT

Adam Bzowski, Paul McFadden, Kostas Skenderis

We present a complete momentum-space prescription for the renormalisation of tensorial correlators in conformal field theories. Our discussion covers all 3-point functions of stres…

Rigid limit for hypermultiplets and five-dimensional gauge theories

Sergei Alexandrov, Sibasish Banerjee, Pietro Longhi

We study the rigid limit of a class of hypermultiplet moduli spaces appearing in Calabi-Yau compactifications of type IIB string theory, which is induced by a local limit of the Ca…

An integrable Lorentz-breaking deformation of two-dimensional CFTs

Monica Guica

It has been recently shown that the deformation of an arbitrary two-dimensional conformal field theory by the composite irrelevant operator , built from the components of…

The Five-Loop Four-Point Integrand of N=8 Supergravity as a Generalized Double Copy

Zvi Bern, John Joseph M. Carrasco, Wei-Ming Chen +3

We use the recently developed generalized double-copy procedure to construct an integrand for the five-loop four-point amplitude of N=8 supergravity. This construction starts from…

Supersymmetric branes and instantons on curved spaces

Ruben Minasian, Daniël Prins, Hagen Triendl

We discuss non-linear instantons in supersymmetric field theories on curved spaces arising from D-branes. Focusing on D3-branes and four-dimensional field theories, we derive the s…

One-loop monodromy relations on single cuts

Alexander Ochirov, Piotr Tourkine, Pierre Vanhove

The discovery of colour-kinematic duality has led to significant progress in the computation of scattering amplitudes in quantum field theories. At tree level, the origin of the du…

Curvature-Squared Multiplets, Evanescent Effects and the U(1) Anomaly in N = 4 Supergravity

Zvi Bern, Alex Edison, David Kosower +1

We evaluate one-loop amplitudes of N = 4 supergravity in D dimensions using the double-copy procedure that expresses gravity integrands in terms of corresponding ones in Yang--Mill…

Four-center bubbled BPS solutions with a Gibbons-Hawking base

Pierre Heidmann

We construct four-center bubbled BPS solutions with a Gibbons-Hawking base space. We give a systematic procedure to build scaling solutions: starting from three-supertube configura…

On Heterotic Vacua with Fermionic Expectation Values

Ruben Minasian, Michela Petrini, Eirik Eik Svanes

We study heterotic backgrounds with non-trivial -flux and non-vanishing expectation values of fermionic bilinears, often referred to as gaugino condensates. The gaugini appear i…

Effective Description of Higher-Order Scalar-Tensor Theories

David Langlois, Michele Mancarella, Karim Noui +1

Most existing theories of dark energy and/or modified gravity, involving a scalar degree of freedom, can be conveniently described within the framework of the Effective Theory of D…

Multiple D3-instantons and mock modular forms II

Sergei Alexandrov, Sibasish Banerjee, Jan Manschot +1

We analyze the modular properties of D3-brane instanton corrections to the hypermultiplet moduli space in type IIB string theory compactified on a Calabi-Yau threefold. In Part I,…

Non-duality in three dimensions

Ilarion V. Melnikov, Ruben Minasian, Savdeep Sethi

We investigate M-theory and heterotic compactifications to 7 and 3 dimensions. In 7 dimensions we discuss a class of massive supergravities that arise from M-theory on K3 and point…

Gravity Amplitudes as Generalized Double Copies

Zvi Bern, John Joseph Carrasco, Wei-Ming Chen +2

Whenever the integrand of a gauge-theory loop amplitude can be arranged into a form where the BCJ duality between color and kinematics is manifest, a corresponding gravity integran…
