Integrable spin chains in twisted maximally supersymmetric Yang-Mills theory

Tim Meier, Stijn J. van Tongeren

We study an angular dipole deformation of maximally supersymmetric Yang-Mills theory (SYM) that preserves its classical scale invariance. We show that two-point functions of suitab…

Scale without conformal invariance from integrable deformations of coset CFTs

Georgios Itsios, Konstantinos Siampos

We construct the $λ$ -model on $S U (3)_{k} / U (2)_{k}$ and we compute the one-loop $β$ -function for the deformation parameter $λ$ . Its non-compact version for $S U (2, 1)_{- k} / U (2)_{- k}$ is a…

Integrated correlators of coincident Wilson lines in $S U (N)$ gauge theories at strong coupling

Lorenzo De Lillo, Alessandro Pini

We consider two four-dimensional gauge theories with gauge group $S U (N)$ : the $N = 4$ Super Yang-Mills (SYM) theory and the $N = 2$ quiver gauge theory obtained as…

The Dark Side of Double-Tensor Multiplets

Laura Andrianopoli, Giuseppe Casale, Lucrezia Ravera +1

We explore the properties of a set of free double-tensor multiplets in $N = 2$ supersymmetry, focusing on their behavior within rigid superspace. These multiplets can be obtained fro…

Mathias Driesse, Gustav Uhre Jakobsen, Albrecht Klemm +5

Using the worldline quantum field theory formalism, we compute the radiation-reacted impulse, scattering angle, radiated energy and recoil of a classical black hole (or neutron sta…

Perturbative bootstrap of the Wilson-line defect CFT: Bulk-defect-defect correlators

Daniele Artico, Julien Barrat, Yingxuan Xu

We study the correlators of bulk and defect half-BPS operators in $N = 4$ Super Yang-Mills theory with a Maldacena-Wilson line defect, focusing on the case involving one bu…

Integrability of the $λ$ -deformation of the PCM with spectators

Riccardo Borsato, Georgios Itsios, J. Luis Miramontes +1

We construct a generalisation of the $λ$ -deformation of the Principal Chiral Model (PCM) where we deform just a subgroup $F$ of the full symmetry group $G$ . We find that demanding…

Gauge independent kinematic algebra of self-dual Yang-Mills theory

Roberto Bonezzi, Felipe Diaz-Jaramillo, Silvia Nagy

The double copy programme relies crucially on the so-called color-kinematics duality which, in turn, is widely believed to descend from a kinematic algebra possessed by gauge theor…
