Energy Correlators in Particle Physics, QFT and Gravity
Ian Moult - Yale University
Detector operators, of which the average null energy operator provides the most famous example, arise as direct theoretical models of asymptotic measurements in collider experiments. In QFT, detector operators are expressed in terms of "light-ray operators", whose correlation functions provide an… -

Towards a double-copy picture in AdS
Maria Nocchi - University of Oxford
The Kawai–Lewellen–Tye (KLT) relations are a striking example of how string theory can reveal hidden structures and connect a web of, in principle, very different theories. Originally, they state that (tree-level) closed-string amplitudes can be expressed as quadratic combinations of open-string… -
Monodromy relations for string amplitudes on AdS
Rodrigo Schmidt Pitombo - Universidade Estadual Paulista (UNESP) - Instituto de Física Teórica (IFP) - São Paulo
String scattering amplitudes are computed from worldsheet integrals of 2D CFT correlators, which leads to a variety of interesting properties. Among the most important are the monodromy relations satisfied by open string amplitudes in flat space. They give non-trivial relations between gluon… -
2+2=4: a 2d/2d unitary/non-unitary correspondence
Motivated by the observation that 2 + 2 = 4, we consider 4d N=2 SCFTs on S^2 x Sigma. On the one hand, reduction of a 4d theory T on a Riemann surface Sigma leads to a family F[T;Sigma] of 2d (2,2) unitary SCFTs, a 2d analog of the 4d theories of class S. On the other hand, reduction on S^2 yields a… -
Irrational CFTs from coupled anyon chains?
Antonio Antunes - École Normale Supérieure - Laboratoire de Physique de l'ENS (LPENS)
Irrational CFTs in 1+1d with a discrete spectrum and no conserved currents other than the stress-tensor are expected to be generic, unsolvable by standard methods, and hard to construct explicitly. In this talk, I will discuss a lattice model that realizes a candidate for such a CFT as a conformal… -
Fortuitous states for 4d black holes
Connor Behan - Perimeter Institute for Theoretical Physics
The AdS/CFT correspondence makes it possible in principle to study explicit black hole microstates using field theory techniques. In practice, this is still difficult because the field theory is only dual to gravity when it is strongly coupled. A more modest goal is to focus on supersymmetric black… -
Soft Charges and Energy-Energy Correlators in the 'in-in' Formalism
Sruthi Narayanan - Perimeter Institute for Theoretical Physics
Recently there has been significant interest in energy-energy correlators which measure the energy flux created at the point of collision by calorimeter-like detectors at asymptotically large distances. The primary building blocks of these observables are Average Null Energy operators (ANECs) which… -
Generalized Entanglement Wedges and Holographic Scattering
Sabrina Pasterski - Perimeter Institute for Theoretical Physics
We use the framework of generalized entanglement wedges to revisit the connected wedge theorem (CWT). First, we establish new upper and lower bounds on the mutual information of boundary decision regions in terms of the entropies of certain bulk scattering regions. Then, we recast the CWT into a… -
RG flows from perturbed 2d CFT - Quantum Fields & Strings Seminar
In this talk we characterize RG flows from UV fixed point described by a 2d CFT perturbed by one of its relevant operators. The first part focuses on rational CFTs. By matching the anomalies associated to their non-invertible symmetries, one conjectures infinitely many new RG flows between Minimal… -
