The Classical Gravitational Impulse at High Energies

The pith
Resumming high-energy scattering amplitudes recovers the all-order classical gravitational impulse for ultrarelativistic particles.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
We compute the gravitational impulse for two classical massive scalars in the ultrarelativistic limit to all orders in Newton's constant G_N at fixed G_N s/m b to O(m^4/s^2). By computing the 4 and 5-point scattering amplitudes in the small-mass regime of -t∼m², we are able to resum all large G_N s corrections. Applying the KMOC formula for the impulse and taking the large mass limit, we recover the classical result at high energies. This resummation agrees with known results in the post-Minkowski expansion, and in the massless limit recovers previous results for the radiated energy. The resummed amplitude predicts the leading high-energy behavior of the PM expansion to eleventh post-Minkowk
What carries the argument
Resummation of large G_N s corrections via 4- and 5-point amplitudes in the -t ~ m² regime, then KMOC formula and large mass limit
Load-bearing premise
The KMOC formula can be applied directly to the resummed amplitudes from the small-mass regime without missing contributions beyond O(m^4/s²) after taking the large-mass limit.
What would settle it
An independent computation of the gravitational impulse or the eleventh-order post-Minkowski coefficient in the high-energy limit that differs from the prediction obtained via this resummation.

We compute the gravitational impulse for two classical massive scalars in the ultrarelativistic limit to all orders in Newton's constant $G_N$ at fixed $G_N s/m b$ to $O(m^4/s^2)$. By computing the 4 and 5-point scattering amplitudes in the small-mass regime of $-t\sim m^2$, we are able to resum all large $G_N s$ corrections. Applying the KMOC formula for the impulse and taking the large mass limit, we recover the classical result at high energies. This resummation is in complete agreement with known results in the post-Minkowski expansion, and in the massless limit we recover previous results for the radiated energy. We use this resummed amplitude to predict the leading high-energy behavior of the PM expansion to eleventh post-Minkowski order.

Referee Report
Summary. The paper computes the gravitational impulse for two classical massive scalars in the ultrarelativistic limit to all orders in G_N at fixed G_N s/(m b) up to O(m^4/s²). It achieves this by evaluating 4- and 5-point scattering amplitudes in the small-mass regime -t ∼ m², resumming all large G_N s corrections there, applying the KMOC impulse formula, and finally taking the large-mass limit. The resulting resummed amplitude agrees with known post-Minkowski results where they can be checked and is used to predict the leading high-energy behavior of the PM expansion through eleventh order; the massless limit recovers prior results for radiated energy.
Significance. If the resummation and subsequent limit interchange are valid without omissions, the work supplies a concrete route to high-order PM coefficients at high energies and demonstrates consistency with existing lower-order results. This would be a useful addition to the classical-gravity literature, particularly for organizing the high-energy expansion of the impulse.
major comments (1)
- [Abstract and KMOC/large-mass-limit section] The central procedure—resumming amplitudes in the regime -t ∼ m², applying KMOC, then taking m → ∞—requires an explicit demonstration that no terms power-suppressed inside the small-mass regime become O(m^4/s²) after the limit and are therefore missed. The abstract and the section describing the KMOC application and large-mass limit state agreement with known PM results up to accessible orders, but do not exhibit an error estimate or cross-check that rules out such hidden contributions at the precision needed for the eleventh-PM prediction.
minor comments (2)
- Clarify the precise definition of the fixed combination G_N s/(m b) and its relation to the impact parameter throughout the resummation.
- Add a short table or explicit list of the PM orders against which the resummed result has been checked, including the numerical or analytic agreement achieved.

Referee: [Abstract and KMOC/large-mass-limit section] The central procedure—resumming amplitudes in the regime -t ∼ m², applying KMOC, then taking m → ∞—requires an explicit demonstration that no terms power-suppressed inside the small-mass regime become O(m^4/s²) after the limit and are therefore missed. The abstract and the section describing the KMOC application and large-mass limit state agreement with known PM results up to accessible orders, but do not exhibit an error estimate or cross-check that rules out such hidden contributions at the precision needed for the eleventh-PM prediction.
Authors: We appreciate the referee's emphasis on rigorously justifying the interchange of limits. The amplitudes are computed in the small-mass regime -t ∼ m² while retaining all contributions not suppressed by positive powers of m²/s at fixed G_N s/(m b). When the KMOC formula is applied and the large-mass limit is subsequently taken, any power-suppressed terms in the small-mass expansion contribute only beyond O(m^4/s²) to the impulse due to the scaling with s and m. The complete agreement with all available post-Minkowski results up to the orders where direct comparison is possible provides a non-trivial consistency check on this power counting. We acknowledge that an explicit error estimate would strengthen the presentation of the eleventh-PM prediction. We will revise the relevant section to include a dedicated discussion of the power counting that demonstrates no relevant terms are missed at the stated precision. revision: yes
Circularity Check
Derivation from amplitude computations is self-contained with no circular reductions
full rationale
The paper computes 4- and 5-point scattering amplitudes explicitly in the small-mass regime -t ~ m², resums the large G_N s corrections there, applies the KMOC impulse formula, and only afterward takes the large-mass limit to recover the classical high-energy result. This chain begins from independent amplitude calculations rather than from the target impulse or PM coefficients. The resulting resummed expression is checked for agreement with known post-Minkowski results up to accessible orders and is used to extrapolate the leading high-energy behavior at 11 PM; the extrapolation is an output of the resummation, not a fitted input renamed as a prediction. No equation or step is shown to equal its own input by construction, and no load-bearing premise rests solely on a self-citation whose content is itself unverified. The derivation therefore remains self-contained against external benchmarks.
Axiom & Free-Parameter Ledger
axioms (2)
- domain assumption The KMOC formula extracts the classical impulse from the resummed scattering amplitudes after the large-mass limit.
- domain assumption The small-mass regime -t ∼ m² captures all relevant large G_N s corrections up to O(m^4/s²).

The radiated momentum may be computed from the impulse via momentum conservation: Rµ =−∆p µ 1 −∆p µ 2 .(4) The system is symmetric under exchange of the projec- tiles, so ∆p µ 2 may then be obtained from ∆p µ 1 under the exchange 1↔2,b→ −bandn↔¯n. Within the EFT framework we are working in, the sum over states implicitly contains a sum over modes, which m...
