Referee report
The paper

The paper claims

An effective field theory reproduces the standard threshold resummation for Higgs production.

The reading

The paper proposes an effective-field-theory route to summing the large soft-gluon logarithms that spoil fixed-order QCD predictions for Higgs production near threshold. The strategy splits the physics by scale: matching at the Higgs mass, running down to an intermediate scale $M_H/N$, and then evolving the parton distributions to $M_H$. The central demonstration is that the resulting resummed coefficient, expanded through N$^3$LL, reproduces the standard pQCD factorization answer, including the coefficient $D_g^{(3)}$ that had recently been computed by the conventional method. A reader should care because an independent derivation of the same resummation checks the standard formalism and gives a template for other production processes.

What carries the argument

The machinery is a scale-by-scale factorization of the gluon-Higgs coefficient function. A matching coefficient $C_g$ is extracted at $M_H$ from the gluon form factor, evolved down to $M_H/N$ with an anomalous dimension built from the cusp anomalous dimension $A_g$ and the soft coefficients $B_{1,g}$, and then connected to the parton distributions by DGLAP evolution. The matching coefficient $M_N$ at the intermediate scale is computed from full QCD in the soft limit, and the final resummed factor $G_N(M_H)$ is assembled from $|C|^2$, $M_N$, and the evolution exponentials. The decomposition $I=I_0+2B_2+2B_1+2B_0$ is what turns this EFT product into the standard resummation formula and defines the $D_g$ coefficients.

Extended reading notes

Core claim

The paper argues that the EFT matching and evolution can be reorganized into exactly the conventional threshold-resummation formula, order by order in the large logarithms. Its central identity is $I=I_0+2B_2+2B_1+2B_0$ in the exponent, and the paper states that this structure is valid to all orders in leading and sub-leading logarithms. Solving the resulting relations iteratively yields $D_g^{(1)}=0$, $D_g^{(2)}$, and the explicit $D_g^{(3)}$ in Eq. (26). The paper states that this $D_g^{(3)}$ agrees completely with the recent conventional calculations of Refs. [9,10], which is the concrete evidence offered for the equivalence at N$^3$LL.

Load-bearing premise

The load-bearing premise is that the all-orders exponentiation encoded in Eqs. (20)-(23), especially the decomposition $I=I_0+2B_2+2B_1+2B_0$ and the definition of $D_g$, is correct; the paper derives this structure only in outline, calling it 'a matter of some technical steps,' and verifies it explicitly only at N$^3$LL.

Editorial extensions

If this is right

  • The same EFT matching and evolution can be applied to Drell-Yan production of $\gamma^*$, $W$, and $Z$ bosons, where only color factors change.
  • Including the newly reproduced $D_g^{(3)}$ term should reduce the residual scale uncertainty in threshold-resummed Higgs production rates.
  • The method provides an independent cross-check of the conventional pQCD resummation at N$^3$LL and can be extended to other observables that suffer from soft-gluon double logarithms.
  • If the all-orders structure holds, the $D_g$ coefficients can be generated iteratively from known anomalous dimensions and matching coefficients rather than from a new full resummation calculation each time.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • The paper's scale-separation logic suggests that threshold resummation is not tied to the details of a soft-collinear Lagrangian; any correct matching onto light-cone operators should give the same $D_g$ coefficients.
  • If the EFT route is reliable, it could be used to predict the next tower of logarithms for processes where the conventional calculation is cumbersome, such as joint threshold and small-$x$ resummation.
  • A natural extension is to check whether the same decomposition organizes rapidity-dependent or transverse-momentum-dependent observables, where the relevant soft function has more than one scale.
Original abstract

We present an effective field theory to resum the large double logarithms originated from soft-gluon radiations at small final-state hadron invariant masses in Higgs and vector boson (\gamma^*, $W$ and $Z$) production at hadron colliders. The approach is conceptually simple, indepaendent of details of an effective field theory formulation, and valid to all orders in sub-leading logarithms. As an example, we show the result of summing the next-to-next-to-next leading logarithms is identical to that of standard pQCD factorization method.
