Energy correlations and Planckian collisions / Chen, Hao (Zhejiang U., Inst. Mod. Phys.) ; Karlsson, Robin (CERN) ; Zhiboedov, Alexander (CERN)
Energy correlations characterize the energy flux through detectors at infinity produced in a collision event. [...]

What is the graviton pole made of? / Häring, Kelian (Delta ITP, Amsterdam ; EPFL, Lausanne, FSL ; CERN) ; Zhiboedov, Alexander (CERN)
We explore the physical mechanisms responsible for generating the graviton pole in twice-subtracted dispersion relations, both in flat space and in AdS. [...]

Generalizing event shapes: In search of lost collider time / Korchemsky, Gregory P. (IPhT, Saclay) ; Sokatchev, Emery (CERN ; Annecy, LAPTH) ; Zhiboedov, Alexander (CERN)
We introduce a new class of collider-type observables in conformal field theories which we call generalized event shapes. They are defined as matrix elements of light-ray operators that are sensitive to the longitudinal, or time-dependent, structure of the state produced in the collision. [...]

A thermal product formula / Dodelson, Matthew (CERN) ; Iossa, Cristoforo (SISSA, Trieste ; INFN, Trieste) ; Karlsson, Robin (CERN) ; Zhiboedov, Alexander (CERN)
We show that holographic thermal two-sided two-point correlators take the form of a product over quasi-normal modes (QNMs). Due to this fact, the two-point function admits a natural dispersive representation with a positive discontinuity at the location of QNMs. [...]

Black hole bulk-cone singularities / Dodelson, Matthew (CERN) ; Iossa, Cristoforo (Geneva U. ; SISSA, Trieste ; INFN, Trieste) ; Karlsson, Robin (CERN) ; Lupsasca, Alexandru (Vanderbilt U.) ; Zhiboedov, Alexander (CERN)
Lorentzian correlators of local operators exhibit surprising singularities in theories with gravity duals. These are associated with null geodesics in an emergent bulk geometry. [...]

Scattering from production in 2d / Tourkine, Piotr (Paris, LPTHE ; CERN) ; Zhiboedov, Alexander (CERN)
In 1968, Atkinson proved the existence of functions that satisfy all S-matrix axioms in four spacetime dimensions. His proof is constructive and to our knowledge it is the only result of this type. [...]

Snowmass White Paper: The Analytic Conformal Bootstrap / Hartman, Thomas (Cornell U.) ; Mazac, Dalimil (Princeton, Inst. Advanced Study) ; Simmons-Duffin, David (Caltech) ; Zhiboedov, Alexander (CERN)
The analytic conformal bootstrap is an array of techniques to characterize, constrain, and solve strongly interacting quantum field theories using symmetries, causality, unitarity, and other general principles. [...]

Scattering amplitudes from dispersive iterations of unitarity / Tourkine, Piotr (Annecy, LAPTH) ; Zhiboedov, Alexander (CERN)
We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions. The algorithm is based on the Mandelstam representation of the amplitude and iterations of unitarity. [...]

An Analytical Toolkit for the S-matrix Bootstrap / Correia, Miguel (CERN ; Ecole Polytechnique, Lausanne) ; Sever, Amit (CERN ; Tel Aviv U.) ; Zhiboedov, Alexander (CERN)
We revisit analytical methods for constraining the nonperturbative $S$-matrix of unitary, relativistic, gapped theories in $d \geq 3$ spacetime dimensions. We assume extended analyticity of the two-to-two scattering amplitude and use it together with elastic unitarity to develop two natural expansions of the amplitude. [...]

Scaling Violation in Power Corrections to Energy Correlators from the Light-Ray Operator Product Expansion / Chen, Hao (Zhejiang U., Inst. Mod. Phys.) ; Monni, Pier Francesco (CERN) ; Xu, Zhen (Zhejiang U., Inst. Mod. Phys.) ; Zhu, Hua Xing (Peking U. ; Peking U., CHEP)
In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. In this Letter we initiate a novel study of the non-perturbative power corrections to the projected $N$-point energy correlators in the limit where the angle between the detectors is small. [...]
