Pith's verdict: This is a retraction notice, not a paper; the authors did the right thing by withdrawing, but there is no technical content left to peer review.

T0 · AI review

How this review was made: An AI referee (deepseek-v4-flash) read the paper on August 28, 2026 and answered a fixed list of questions about it. T0 is the starting level every paper gets. The levels describe how deeply Pith has checked the paper, never the authors.

T0 AI review An AI read the paper and answered a fixed list of questions.

Editor's note

read the letter

The one thing you should know: arXiv:hep-ph/0602208v2 is a two-sentence withdrawal notice. The authors state that an error in their diagram evaluation invalidates the conclusion of their earlier comment, and they withdraw the paper. That is the entire content. There is no new analysis, no corrected calculation, no replacement result, and no surviving argument to assess.

What the paper does well is honesty. The authors caught an error in their own work and publicly retracted it. That is exactly how the scientific record should work, and it deserves credit. A retraction that says plainly "we made a mistake, our conclusion is invalid" is more useful to the community than a silent vanishing or a stubborn defense of a broken claim.

That said, there is nothing here that peer review can engage with. The reader's REJECT verdict is correct in the narrow sense that this is not a research contribution. The stress-test note points out that the invalidation cannot be independently confirmed because the corrected diagram evaluation is not shown. That is true, but it is not a flaw in a retraction. A withdrawal is not a new result and does not carry the burden of proof that a new calculation would. The authors are not asking us to accept a new conclusion; they are telling us to ignore their old one. We do not need to see the corrected arithmetic to honor that request.

The only real soft spot is that the notice gives no detail at all, which makes it impossible for a reader to know whether the original comment fails everywhere or just in one numerical point. But that is a minor complaint about a retraction's completeness, not a reason to send this to referees.

Who is this for? Anyone maintaining a citation list, especially in QCD sum rule phenomenology, who needs to know that hep-ph/0602208, if cited anywhere, should now be marked as withdrawn. It is also a small data point for people who study how errors propagate in the literature. For any other purpose, there is nothing to read.

My recommendation: do not send this to peer review. Desk-reject it as a submission, and treat it as an appropriate administrative withdrawal. The authors have already done the scientifically important act by pulling the paper. A referee cannot add anything.

Referee report

Major objections (3)

[Abstract and full text] The claim that 'an error in the evaluation of the diagram, which invalidates our conclusion' is presented without any supporting evidence. The manuscript does not specify which diagram was mis-evaluated, what the error was, what the corrected value is, or why that corrected value overturns the original conclusion. As a result, the central assertion of the retraction cannot be independently checked; the reader is asked to accept the invalidation entirely on the authors' authority. This is a load-bearing omission because this statement is the entire content of the paper.
[Full text] The notice does not distinguish between a localized numerical miscalculation and a materially invalidating error. The wording 'invalidates our conclusion' asserts that the error changes the original conclusion, but no derivation is supplied to show that the corrected diagram alters the final result rather than merely shifting a numerical value. Without that information, readers cannot determine whether the retraction is appropriately scoped or overbroad, which matters for how the original comment should be cited in future work.
[Full text] Because the original v1 text is absent, the reader has no basis to reconstruct which step of the argument the diagram error affects. In particular, the notice does not state whether the error changes the sign of a contribution, its magnitude, or its qualitative role in the sum rule analysis. This lack of context makes it impossible to assess whether the admitted error actually supports the retraction, and it also prevents the community from learning from the mistake.

The paper

The paper claims

The authors withdraw their comment on a light-scalar-meson QCD sum rule study, saying a diagram-evaluation error invalidates its conclusion.

The reading

This paper is a withdrawal notice. The authors report that an error in their evaluation of the diagram invalidates the conclusion of their earlier comment on a QCD sum rule study of the light scalar mesons. The notice gives no details of the error and offers no corrected calculation. A sympathetic reading is simply that the authors no longer stand by the comment's conclusion and are asking readers not to rely on it.

What carries the argument

The load-bearing object is the diagram evaluation in the original comment's QCD sum rule analysis: the specific Feynman-diagram contribution whose computed value supported the comment's conclusion. The paper presents no corrected value; it only states that the discovered error changes the outcome. The machinery matters because the entire retraction rests on that single evaluation being decisive, so the withdrawal is only as strong as that implicit dependence.

Extended reading notes

Core claim

The paper's central claim is that an error was made in evaluating the diagram in the authors' earlier comment on 'A QCD sum rule study of the light scalar mesons,' and that this error invalidates the comment's conclusion. The text does not identify which diagram, what the mistake was, or what a corrected evaluation would give. On the paper's own terms, the discovery is simply that the earlier conclusion cannot stand as written.

Load-bearing premise

The load-bearing premise is that the diagram-evaluation error actually determined the conclusion, rather than being a mistake that a corrected calculation could absorb without changing the result.

Editorial extensions

If this is right

The comment's conclusion that the QCD sum rule study of light scalar mesons is flawed is withdrawn.
Anyone relying on the comment as a critique of that sum rule study should treat that reliance as unsupported.
The original study's results are not refuted by this comment, since the only stated reason for retraction is an error in the comment's own diagram.
The withdrawal supersedes the comment as the authoritative statement of the authors' position.

Reading between the lines

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

Because the notice gives no details of the error, the original comment's numerical results should be treated as unverified, not as shown false; the only established fact is that the authors no longer stand behind the conclusion.
A corrected evaluation of the diagram, if published, would be needed to decide whether the original critique could be repaired or whether the original sum rule study stands.
For readers of the sum rule study, the practical consequence is that this comment is no longer usable as a refutation, while the underlying disagreement about scalar mesons is left unresolved.
