Reciprocal of the CPT theorem
Luis Álvarez-Gaumé, Moshe M. Chaichian, Markku A. Oksanen +1
The CPT theorem originally proven by Lüders and Pauli ensures the equality of masses, lifetimes, magnetic moments and cross sections of any particle and its antiparticle. We show t…
Black hole perturbation theory and multiple polylogarithms
Gleb Aminov, Paolo Arnaudo, Giulio Bonelli +2
We study black hole linear perturbation theory in a four-dimensional Schwarzschild (anti) de Sitter background. When dealing with a positive cosmological constant, the correspondin…
Global magniicence, or: 4G Networks
Nikita Nekrasov, Nicolo Piazzalunga
The global magnificent four theory is the homological version of a maximally supersymmetric -dimensional gauge theory on a Calabi-Yau fourfold fibered over a circle. In the…
Remarks on Boundaries, Anomalies, and Noninvertible Symmetries
Yichul Choi, Brandon C. Rayhaun, Yaman Sanghavi +1
What does it mean for a boundary condition to be symmetric with respect to a non-invertible global symmetry? We discuss two possible definitions in 1+1d. On the one hand, we call a…
Parallel surface defects, Hecke operators, and quantum Hitchin system
Saebyeok Jeong, Norton Lee, Nikita Nekrasov
We examine two types of half-BPS surface defects regular monodromy surface defect and canonical surface defect in four-dimensional gauge theory with supersy…
A Large Twist Limit for Any Operator
Gwenaël Ferrando, Amit Sever, Adar Sharon +1
We argue that for any single-trace operator in SYM theory there is a large twist double-scaling limit in which the Feynman graphs have an iterative structure. Such str…
