OPE coefficients in Argyres-Douglas theories

Agnese Bissi, Francesco Fucito, Andrea Manenti +2

The calculation of physical quantities in certain quantum field theories such as those of the Argyres-Douglas type is notoriously hard, due to the lack of a Lagrangian description.…

Off-Shell Color-Kinematics Duality for Chern-Simons

Maor Ben-Shahar, Henrik Johansson

Many gauge theories possess a hidden duality between color and kinematics in their on-shell scattering amplitudes. An open problem is to formulate an off-shell realization of the d…

Index of the Transversally Elliptic Complex in Pestunization

Roman Mauch, Lorenzo Ruggeri

In this note we present a formula for the equivariant index of the cohomological complex obtained from localization of $N = 2$ SYM on simply-connected compact four-manifold…

Quadratic-in-spin interactions at fifth post-Newtonian order probe new physics

Jung-Wook Kim, Michèle Levi, Zhewei Yin

We obtain for the first time all quadratic-in-spin interactions in spinning binaries at the third subleading order in post-Newtonian (PN) gravity, and provide their observable bind…

Learning Size and Shape of Calabi-Yau Spaces

Magdalena Larfors, Andre Lukas, Fabian Ruehle +1

We present a new machine learning library for computing metrics of string compactification spaces. We benchmark the performance on Monte-Carlo sampled integrals against previous nu…

An effective three-dimensional de Sitter cosmology in string theory

Filip Landgren

Motivated by the lack of consensus on whether or not de Sitter (dS) lies in the Swampland, we use a recently developed braneworld construction and known Anti-de Sitter (AdS) vacua…

Kinematic Hopf Algebra for BCJ Numerators in Heavy-Mass Effective Field Theory and Yang-Mills Theory

Andreas Brandhuber, Gang Chen, Henrik Johansson +2

We present a closed formula for all Bern-Carrasco-Johansson (BCJ) numerators describing $D$ -dimensional tree-level scattering amplitudes in a heavy-mass effective field theory with…

Weyl Anomalies of Four Dimensional Conformal Boundaries and Defects

Adam Chalabi, Christopher P. Herzog, Andy O'Bannon +2

Motivated by questions about quantum information and classification of quantum field theories, we consider Conformal Field Theories (CFTs) in spacetime dimension $d \geq 5$ with a c…

Rebooting quarter-BPS operators in $N = 4$ Super Yang-Mills

Agnese Bissi, Giulia Fardelli, Andrea Manenti

We start a systematic study of quarter-BPS operators in four-dimensional $N = 4$ Super Yang-Mills with gauge group $SU (N)$ making use of recently developed tools i…

Branches, quivers, and ideals for knot complements

Tobias Ekholm, Angus Gruen, Sergei Gukov +4

We generalize the $F_{K}$ invariant, i.e. $Z$ for the complement of a knot $K$ in the 3-sphere, the knots-quivers correspondence, and $A$ -polynomials of knots, and find sev…

Manifest colour-kinematics duality and double-copy in the string-based formalism

Naser Ahmadiniaz, Filippo Maria Balli, Olindo Corradini +3

The relation for the gravity polarisation tensor as the tensor product of two gluon polarisation vectors has been well-known for a long time, but a version of this relation for mul…

SYM on Quotients of Spheres and Complex Projective Spaces

Jim Lundin, Lorenzo Ruggeri

We introduce a generic procedure to reduce a supersymmetric Yang-Mills (SYM) theory along the Hopf fiber of squashed $S^{2 r - 1}$ with $U (1)^{r}$ isometry, down to the $\mathbb{CP}^{r-…

Re-examining the stability of rotating horizonless black shells mimicking Kerr black holes

Ulf Danielsson, Suvendu Giri

In arXiv:1705.10172 a string theory inspired alternative to gravitational collapse was proposed, consisting of a bubble of AdS space made up of ingredients from string theory. Thes…

One-loop Gluon Amplitudes in AdS

Luis F. Alday, Agnese Bissi, Xinan Zhou

We initiate the study of one-loop gluon amplitudes in AdS space. These amplitudes were recently computed at tree level for a variety of backgrounds of the form $AdS_{d+1} \times S^…

Flavor deformations and supersymmetry enhancement in $4 d$ $N = 2$ theories

Usman Naseer, Charles Thull

We study $N = 2$ theories on four-dimensional manifolds that admit a Killing vector $v$ with isolated fixed points. It is possible to deform these theories by coupling posi…

Killing-Yano Cotton Currents

Ulf Lindström, Özgür Sarıoğlu

We discuss conserved currents constructed from the Cotton tensor and (conformal) Killing-Yano tensors (KYTs). We consider the corresponding charges generally and then exemplify wit…

Notes on Worldsheet-Like Variables for Cluster Configuration Spaces

Song He, Yihong Wang, Yong Zhang +1

We continue the exploration of various appearances of cluster algebras in scattering amplitudes and related topics in physics. The cluster configuration spaces generalize the famil…

Phases of $N = 1$ Quivers in $2 + 1$ Dimensions

Vladimir Bashmakov, Nicola Gorini

We consider the IR phases of two-node quiver theories with $N = 1$ supersymmetry in $d = 2 + 1$ dimensions. It turns out that the discussion splits into two main ca…

Evidence for an Algebra of $G_{2}$ Instantons

Michele Del Zotto, Jihwan Oh, Yehao Zhou

In this short note, we present some evidence towards the existence of an algebra of BPS $G_{2}$ instantons. These are instantonic configurations that govern the partition functions o…
