Perturbing the symmetric orbifold from the worldsheet
Marc-Antoine Fiset, Matthias R. Gaberdiel, Kiarash Naderi +1
The symmetric orbifold of is the analogue of free SYM in four dimensions, and its dual is described by a tensionless string propagating in ${\rm AdS}_3\times {\rm S}…
Tunable tachyon mass in the PT-broken massive Thirring model
Benjamin Liegeois, Chitra Ramasubramanian, Nicolo Defenu
We study the full phase diagram of a non-Hermitian PT-symmetric generalization of the paradigmatic two-dimensional massive Thirring model. Employing the non-perturbative functional…
Colour-kinematics duality, double copy, and homotopy algebras
Leron Borsten, Hyungrok Kim, Branislav Jurčo +3
Colour-kinematics duality is a remarkable property of Yang-Mills theory. Its validity implies a relation between gauge theory and gravity scattering amplitudes, known as double cop…
Exposing the threshold structure of loop integrals
Zeno Capatti
The understanding of the physical laws determining the infrared behaviour of amplitudes is a longstanding and topical problem. In this paper, we show that energy conservation alone…
Kinematic Lie Algebras From Twistor Spaces
Leron Borsten, Branislav Jurco, Hyungrok Kim +3
We analyze theories with color-kinematics duality from an algebraic perspective and find that any such theory has an underlying BV-algebra structure…
Double-copy towards supergravity inflation with -attractor models
John Joseph M. Carrasco, Matthew Lewandowski, Nicolas H. Pavao
Key to the simplicity of supergravity -attractor models of inflation are Volkov-Akulov fermions, often in the form of nilpotent superfields. Here we explore the possibility of u…
