The equations are written out explicitly, the N=2 finiteness check in Section II is a genuine nontrivial consistency test that would expose many classes of error, and the Note added records independent agreement with Yamada [34] and Jack-Jones [35]. The soft couplings are inputs, not fitted quantities, so the circularity failure mode does not apply. I therefore do not think the verdict should move toward REJECT or UNVERDICTED. I agree with the reader that the load-bearing vulnerability sits in the MS-to-DR translation and the ε-scalar mass counterterms, and that the acknowledged error history in Eq. (2.20) is the concrete trace of that vulnerability. Where I would sharpen the reader's framing: the reader treats the errors as 'acknowledged and resolved,' but the resolution for (2.20) rests on a prescription whose justification the authors place in a note 'to be reported on elsewhere' and on two preprints rather than a published derivation. That is a located, unresolved item, not merely a stylistic omission of algebra. It is narrow — it does not touch (2.13)-(2.14) or (2.16)-(2.17) — but it propagates into every MSSM scalar-mass beta function, which is the part of the paper with the widest actual use. The concrete test I propose is deliberately internal: the one-loop exactness of the S quantity in (4.27) is a standard structural result, and the S′ and σ₁ terms visible in (4.31)-(4.43) are precisely the pieces that must cancel for it to hold. If they cancel, the corrected (2.20) is at least self-consistent with the MSSM reduction and my concern largely dissolves; if they do not, the correction is incomplete and the CONDITIONAL verdict is if anything too generous. Because the test is cheap and the outcome uncertain, I leave the verdict at UNCHANGED rather than moving to ACCEPT: the reader's CONDITIONAL is the right resting point for a reference paper whose most-used equation carries a self-declared prescription dependence with an off-paper justification.","tokens_in":21143,"tokens_out":3614,"duration_ms":56156,"concrete_test":"Take the printed MSSM equations (4.30)-(4.43) and form the combination S defined in (4.27), summing the two-loop pieces with the weights +1 for m²_Hu, −1 for m²_Hd, +1 for m²_Q, −1 for m²_L, −2 for m²_u, +1 for m²_d, +1 for m²_e. The standard result is that S obeys a one-loop-exact RGE, so the two-loop coefficient of S must cancel identically, with the S′ and σ₁ terms in (4.31), (4.33), (4.35), (4.37), (4.39), (4.41), (4.43) combining to zero. If the cancellation fails, the corrected (2.20) is incomplete or the prescription has not been applied consistently across the MSSM specializations. A symbolic-algebra check suffices; no new loop calculation is required.","verdict_should_be":"UNCHANGED","load_bearing_attack":"The h and b results, (2.13)-(2.14) and (2.16)-(2.17), are corroborated by Yamada [34] and Jack-Jones [35] and pass the N=2 finiteness check of Section II, so I do not regard the unexhibited dummy-scalar bookkeeping as a live correctness risk by itself. The one place where the paper's own text leaves a condition unmet is Eq. (2.20). The Note added states that the original coefficient of the last term, δ^i_j g^4 C(i)(Tr[S(r)m²] − C(G)MM†), was wrong, and that the corrected form 'corresponds to this prescription' — a treatment of the unphysical ε-scalar mass chosen so that the two-loop β functions and the pole-mass relations do not depend on it. That is a scheme choice, not a derivation, and the paper explicitly says 'The subtleties involved will be reported on elsewhere.' No published reference supplies the argument; the support offered is agreement with two preprints [34,35] and an unpublished note. So the load-bearing condition for (2.20) — that the ε-scalar mass counterterms are handled at the order needed and that the resulting prescription is internally consistent — is asserted rather than demonstrated in this manuscript. This matters because (2.20) feeds every MSSM scalar-mass equation (4.30)-(4.43), i.e. the part of the paper most used in spectrum calculations. Note this is narrower than the reader's framing: the concern is not that the derivation is omitted in general, but that for this one equation the authors themselves flag a prescription dependence and route its justification outside the paper.","agreement_with_reader":"partial"},"referee_report":{"model":"selfhosted/deepseek-v4.1-flash","summary":"The manuscript computes the two-loop renormalization group equations for all soft supersymmetry-breaking couplings in a general softly broken N=1 supersymmetric gauge theory: the trilinear couplings h^{ijk} in Eqs.

For completeness it also reviews the known two-loop results for gauge couplings, gaugino masses, and superpotential parameters, and it gives the rules for extending everything to a direct product gauge group in Section III. Section IV specializes the general results to the MSSM, giving the two-loop beta functions for h_u, h_d, h_e in Eqs. (4.18)-(4.23), for B in Eqs. (4.25)-(4.26), and for all scalar masses in Eqs. (4.30)-(4.43). The method is to apply the dummy-scalar trick to the MS-bar results of Machacek and Vaughn [22-24] and then translate to the DR-bar scheme using the authors' one-loop dictionary [20], including one-loop mass counterterms for the epsilon scalars. The paper reports two consistency checks: the general formulas vanish in the constrained N=2 case, and, per the Note added, the corrected Eq. (2.20) and the matrix orderings in Section IV now agree with the independent calculations of Yamada [34] and Jack and Jones [35].","tokens_in":21489,"tokens_out":5128,"duration_ms":79081,"significance":"If correct, this is the definitive reference for two-loop running of soft supersymmetry-breaking parameters, and it has plainly been used that way. The value of the paper is the explicit, complete set of equations rather than a conceptual advance, and the authors have done the field the service of printing every coefficient, keeping complex phases general, and separating M from M* throughout. Two features deserve explicit credit. First, the N=2 finiteness check described at the end of Section II is a genuine, nontrivial consistency test of the whole set of general formulas, not a cosmetic remark. Second, the Note added is a model of transparent correction: it identifies the erroneous coefficient in Eq. (2.20), states that the Section IV results were corrected accordingly, and credits the groups that found the discrepancy. The results are falsifiable in the practical sense that they can be checked against direct DRED calculations and against spectrum codes, and they have been.","major_comments":[{"comment":"This is the one place where the manuscript's own text leaves a condition unmet, and the authors acknowledge it.

Neither the subtraction condition nor the redefinition is exhibited, and the justification is deferred to a note 'to be reported on elsewhere.' Because Eq. (2.20) feeds every MSSM scalar-mass equation (4.30)-(4.43), a reader cannot verify from this manuscript alone that the printed equation is prescription-independent at the order claimed. I recommend a short appendix giving the epsilon-scalar mass counterterm treatment and the explicit redefinition relating the two prescriptions, or at minimum a precise statement of the subtraction condition that defines the scheme. I want to be clear that this is a transparency and reproducibility request, not a challenge to the result: the equation as printed is corroborated by the independent calculations of [34] and [35], and the risk that it is wrong is correspondingly low.","section":"Eq.

The new content is (2.13)-(2.20) — the two-loop beta functions for h^{ijk}, b^{ij}, and (m^2)^j_i — plus the full MSSM specialization (4.18)-(4.43). The rest of Section II reviews known gauge, superpotential, and gaugino-mass results and says so plainly, which is the right call for a paper people will use as a lookup table [abstract:s0]. The equations are written out completely, with no compressed notation, so you can implement them directly. The N=2 finiteness check at the end of Section II is a real test, not decoration: the general formulas collapse to zero under the appropriate constraints, and that is hard to fake. The Note added is also honest — it records that Eq. (2.20) and some matrix orderings in Section IV were wrong in the original version and were fixed after comparison with Yamada and Jack-Jones. Where I would push is narrow. The derivation is deliberately not shown (we decline to exhibit the details here), and for most of the paper that is fine, because the dummy-scalar bookkeeping is mechanical and the results are corroborated. Eq. (2.20) is the exception. The Note added says the corrected coefficient corresponds to a prescription for the epsilon-scalar mass, chosen so the two-loop betas and the pole-mass relations do not depend on it, and then defers the argument to a note to be reported on elsewhere. That is a scheme choice asserted rather than derived, and the support at that point is two preprints rather than published work. Since (2.20) feeds every scalar-mass equation in Section IV, that is the one place where I would want the follow-up before trusting the last term at full precision.

This paper computes, for the first time, the two-loop $\\beta$ functions for all three classes of soft-breaking couplings in a general $N=1$ supersymmetric gauge theory: the trilinear scalar couplings $h^{ijk}$, the bilinear $b^{ij}$, and the scalar mass-squared matrix $(m^2)^j_i$. It then specializes every equation to the Minimal Supersymmetric Standard Model, writing out the running of $h_u, h_d, h_e$, of $B$, and of all seven scalar mass-squared parameters including the off-diagonal family-space matrices.

Two-loop beta functions for a general renormalizable theory were already known in dimensional regularization, but dimensional regularization breaks supersymmetry by mismatching gauge boson and gaugino degrees of freedom, so supersymmetric results must be quoted in dimensional reduction instead. The authors take the known general results and promote dimensionful couplings to dimensionless ones by adjoining non-propagating dummy scalar fields: a fermion mass becomes a Yukawa coupling to a dummy scalar, a scalar mass-squared becomes a quartic coupling with two dummy scalars, and a trilinear scalar coupling becomes a quartic coupling with one dummy scalar. Careful combinatorics on symmetry factors then extracts the beta function for the dimensionful coupling. Finally the results are converted from modified minimal subtraction to the supersymmetric modified minimal subtraction scheme using a one-loop dictionary supplied in the authors' earlier work, including one-loop mass counterterms for the unphysical epsilon-scalar fields that dimensional reduction introduces. The paper states that this procedure is straightforward but tedious and declines to exhibit the intermediate steps.","core_discovery":"The claim is completeness: the paper presents the full set of two-loop renormalization group equations for the soft supersymmetry-breaking sector of a general softly broken $N=1$ supersymmetric model, closing the last gap left by earlier work on gauge couplings, gaugino masses and superpotential parameters.

(2.19)-(2.20) for the scalar masses $(m^2)^j_i$, each written as a one-loop piece plus a two-loop piece, with no assumption about the complex phases of the parameters. Section III gives the replacement rules needed when the gauge group is a product of simple factors and for the special case of more than one $U(1)$. Section IV then translates everything into the MSSM, listing the two-loop $\\beta$ functions for $h_u, h_d, h_e$ (Eqs. 4.18-4.23), for $B$ (4.25-4.26), and for $m^2_{H_u}, m^2_{H_d}, m^2_Q, m^2_L, m^2_u, m^2_d, m^2_e$ (4.30-4.43), the last five being $3$ by $3$ matrices in family space.
