Conformal Colliders Meet the LHC* / Moult, Ian (speaker) (Yale University)
Jets of hadrons produced at high-energy colliders provide experimental access to the dynamics of asymptotically free quarks and gluons and their confinement into hadrons. Motivated by recent developments in conformal field theory, we show that questions of interest in collider physics can be reformulated as the study of correlation functions of a specific class of light-ray operators and their associated operator product expansion (OPE).

Transverse spin in the light-ray OPE / Chang, Cyuan-Han (Caltech, Pasadena (main)) ; Kologlu, Murat (Oxford U., Inst. Math.) ; Kravchuk, Petr (Princeton, Inst. Advanced Study) ; Simmons-Duffin, David (Caltech, Pasadena (main)) ; Zhiboedov, Alexander (CERN)
We study a product of null-integrated local operators $\mathcal{O}_1$ and $\mathcal{O}_2$ on the same null plane in a CFT. Such null-integrated operators transform like primaries in a fictitious $d-2$ dimensional CFT in the directions transverse to the null integrals. [...]

Energy correlations in heavy states / Chicherin, Dmitry (Annecy, LAPTH) ; Korchemsky, Gregory P. (IPhT, Saclay ; IHES, Bures-sur-Yvette) ; Sokatchev, Emery (Annecy, LAPTH) ; Zhiboedov, Alexander (CERN)
We study energy correlations in states created by a heavy operator acting on the vacuum in a conformal field theory. We argue that the energy correlations in such states exhibit two characteristic regimes as functions of the angular separations between the calorimeters: power-like growth at small angles described by the light-ray OPE and slowly varying, or ``flat'', function at larger angles. [...]

The light-ray OPE and conformal colliders / Kologlu, Murat (Caltech) ; Kravchuk, Petr (CERN) ; Simmons-Duffin, David (Caltech) ; Zhiboedov, Alexander (CERN)
We derive a nonperturbative, convergent operator product expansion (OPE) for null-integrated operators on the same null plane in a CFT. The objects appearing in the expansion are light-ray operators, whose matrix elements can be computed by the generalized Lorentzian inversion formula. [...]

Light ray operators, detectors, and energy correlators / Simmons-Duffin, David (speaker) (CalTech)
Light ray operators control many aspects of Lorentzian physics in quantum field theory. For example, they describe the behavior of correlators at large boost, and also provide a natural basis for collider measurements. [...]

On the light-ray algebra in conformal field theories / Korchemsky, Gregory P. (IPhT, Saclay ; IHES, Bures-sur-Yvette) ; Zhiboedov, Alexander (CERN)
We analyze the commutation relations of light-ray operators in conformal field theories. We first establish the algebra of light-ray operators built out of higher spin currents in free CFTs and find explicit expressions for the corresponding structure constants. [...]

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. [...]

On the Stress Tensor Light-ray Operator Algebra / Belin, Alexandre (CERN) ; Hofman, Diego M. (U. Amsterdam, IHEF) ; Mathys, Grégoire (U. Amsterdam, IHEF) ; Walters, Matthew T. (Ecole Polytechnique, Lausanne)
We study correlation functions involving generalized ANEC operators of the form $\int dx^- \left(x^-\right)^{n+2} T_{--}(\vec{x})$ in four dimensions. We compute two, three, and four-point functions involving external scalar states in both free and holographic Conformal Field Theories. [...]

Celestial amplitudes: from UV constraints to conformal blocks / Ana-Maria, Raclariu (speaker)
Celestial amplitudes describe scattering in a basis of boost eigenstates. In this basis, 4-point scattering is characterized by two variables: the sum over the boost weights $\beta$ which is dual to the center of mass energy, and a cross ratio $z$ related to the bulk scattering angle. [...]
