What was already known
The earlier gluon calculation concerns Yang–Mills theory. This paper derives the corresponding gravity recursion and solution; the generic-kinematics vanishing argument does not cover its special configurations.
What changed and why it matters
Extends a special-kinematics amplitude calculation to gravity with a new recursion and general solution. This is a distinct gravity result related to the gluon paper.
The AI contribution
The authors credit GPT-5.2 Pro and an internal OpenAI model with significant roles throughout the project. The source does not allocate every derivation step between the models and the human researchers.
Limitations
Applies in Klein space or with complexified momenta. The Ward-identity conclusion also needs analyticity assumptions. This is not a proof of quantum gravity or an experimental detection. AIProofWatch has not independently checked the argument.
Verification evidence
Evidence labels show what supports the claim. Importance rates its impact if correct.
Author claim
The authors report the gravity recursion, tree-sum solution and restricted product formula.
Accessible artifact / proof
Accessible derivation and explicit AI disclosure; no independent check asserted here.
Correction and publication history
