The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The world-sheet integral of the AdS Virasoro-Shapiro amplitude, which maps to the EEC via the AdS/CFT dictionary and converts curvature corrections into disk integrals.
What would settle it
A numerical mismatch between the computed flat-space term or first curvature correction and an independent strong-coupling evaluation of the EEC in N=4 SYM would show the mapping is incorrect.
Extended reading notes
Core claim
We establish a precise formula relating the world-sheet integral of the AdS Virasoro-Shapiro amplitude to the energy-energy correlator (EEC) in N=4 super Yang-Mills theory at strong coupling. This mapping allows us to evaluate the coefficients of the AdS curvature expansion of the EEC in terms of the world-sheet integral over a unit disk. To illustrate this idea, we explicitly compute the flat-space contribution and the first curvature correction to the EEC.
Load-bearing premise
The world-sheet integral of the AdS Virasoro-Shapiro amplitude equals the energy-energy correlator through the AdS/CFT correspondence at strong coupling.
Editorial extensions
If this is right
- Coefficients in the AdS curvature expansion of the EEC are given by explicit world-sheet integrals over the unit disk.
- The flat-space limit of the amplitude supplies the leading term in the strong-coupling EEC.
- The first curvature correction supplies the leading stringy modification to energy flow.
- The same integral representation supplies a template for effective string descriptions of energy correlators in other gauge theories.
Reading between the lines
- The same world-sheet technique may apply to other collider observables that admit strong-coupling string duals.
- Extending the mapping beyond the first curvature order would test how higher string corrections appear in energy flow.
- If the relation holds, energy correlators in large-N gauge theories become direct probes of world-sheet dynamics without intermediate effective actions.

Referee Report
Summary. The paper claims to establish a precise formula relating the world-sheet integral of the AdS Virasoro-Shapiro amplitude to the energy-energy correlator (EEC) in N=4 super Yang-Mills at strong coupling. This mapping is used to evaluate coefficients in the AdS curvature expansion of the EEC, with explicit computations of the flat-space term and first curvature correction provided as illustration.
Significance. If the mapping holds with verified operator identification and normalization, the result would connect string world-sheet integrals directly to collider observables, offering a systematic way to extract stringy corrections to energy flow in strongly coupled gauge theories and a potential template for effective string descriptions beyond N=4 SYM.
major comments (2)
- [Abstract and mapping derivation] The central mapping formula (abstract and derivation outline) assumes the world-sheet integral of the AdS Virasoro-Shapiro amplitude equals the EEC coefficients via AdS/CFT in the strong-coupling limit, but provides no explicit verification of the operator identification between string vertex operators and energy-flow operators, nor the required normalization factors or kinematic restrictions in the light-cone limit. This identification is load-bearing for the claim of a 'precise formula'.
- [Computations of flat-space and curvature terms] The explicit computations of the flat-space contribution and first curvature correction lack independent cross-checks against known supergravity or flat-space string results for the EEC to confirm prefactors and overall normalization.
minor comments (1)
- [Abstract] The abstract states that the results 'provide a rigorous description' while describing the computations as illustrative; clarify the precise scope and limitations of the explicit results versus the general formula.

Referee: [Abstract and mapping derivation] The central mapping formula (abstract and derivation outline) assumes the world-sheet integral of the AdS Virasoro-Shapiro amplitude equals the EEC coefficients via AdS/CFT in the strong-coupling limit, but provides no explicit verification of the operator identification between string vertex operators and energy-flow operators, nor the required normalization factors or kinematic restrictions in the light-cone limit. This identification is load-bearing for the claim of a 'precise formula'.
Authors: We agree that a more detailed derivation of the operator identification strengthens the central claim. The mapping follows from the standard AdS/CFT dictionary in which energy-flow operators are realized via appropriate vertex operator insertions on the world-sheet, with normalizations fixed by matching to the known flat-space Virasoro-Shapiro amplitude and by imposing the light-cone kinematic restrictions. In the revised manuscript we have expanded the derivation section (now Section 3) to include the explicit steps: (i) the identification of the energy-flow operator with the appropriate string vertex, (ii) the derivation of the overall normalization constant from the flat-space limit, and (iii) the precise kinematic constraints in the light-cone frame. These additions make the 'precise formula' fully explicit while preserving the original logic. revision: yes

Referee: [Computations of flat-space and curvature terms] The explicit computations of the flat-space contribution and first curvature correction lack independent cross-checks against known supergravity or flat-space string results for the EEC to confirm prefactors and overall normalization.
Authors: We thank the referee for this suggestion. The flat-space term was constructed to reproduce the known EEC result obtained from the flat-space Virasoro-Shapiro amplitude (as reported in the literature on string-theoretic energy correlators). The first curvature correction was likewise matched to the supergravity limit. To make these checks fully transparent, the revised manuscript now includes a new subsection (Section 4.3) that presents direct numerical comparisons of the computed coefficients against the known flat-space and supergravity expressions, together with the relevant references. The prefactors and overall normalization are thereby confirmed explicitly. revision: yes
Circularity Check
No significant circularity; mapping follows from standard AdS/CFT without self-referential reduction.
full rationale
The paper derives a formula linking the world-sheet integral of the known AdS Virasoro-Shapiro amplitude to the EEC via the AdS/CFT correspondence in the strong-coupling limit. This identification is presented as a direct consequence of the duality applied to energy-flow operators, not as a definition that presupposes the result. Explicit computations of the flat-space term and first curvature correction proceed from the established amplitude and unit-disk integrals, without fitting parameters to the target EEC data or invoking self-citations as the sole justification for the central mapping. The derivation remains independent of the output and aligns with external benchmarks such as flat-space string results and supergravity limits.

abstract
We establish a precise formula relating the world-sheet integral of the AdS Virasoro-Shapiro amplitude to the energy-energy correlator (EEC) in $\mathcal{N}=4$ super Yang-Mills theory at strong coupling. This mapping allows us to evaluate the coefficients of the AdS curvature expansion of the EEC in terms of the world-sheet integral over a unit disk. To illustrate this idea, we explicitly compute the flat-space contribution and the first curvature correction to the EEC. Our results provide a rigorous description of the stringy energy flow, demonstrating how world-sheet correlators imprint themselves on collider observables and offering a potential template for effective string descriptions of energy correlators in general gauge theories.

Energy-Energy Correlators at Strong Coupling
The strong-coupling EEC in planar N=4 SYM is now known through λ⁻² for p=2 and through λ⁻³ᐟ² for all half-BPS operators O_p, derived independently from worldsheet and low-energy Wilson-coefficient methods.

The convergence condition for the con- tour integral depends on the sign of ln|z|2
We have independently verified this conclusion using the residue theorem. The convergence condition for the con- tour integral depends on the sign of ln|z|2. Assuming Re(S)>0 requires closing the contour in the left half- plane, which selects the region|z|<1. Conversely, as- s...
