Single-source concentration cap (sources.md): this is an unrefereed arXiv preprint (single author, no stated peer review). All three claims below rest on it directly, which reaches but does not exceed the cap of three claim-notes per unrefereed primary absent independent corroboration. Several other findable claims in the same paper (the Jensen–Shannon divergence stability result, the primary-order classification audit, the candidate-family prominence asymmetry in Figure 2) were accordingly held back to Further leads rather than written up as a fourth or fifth claim.
All claims below rest on this arXiv preprint (Tier 1 — primary, the author's own data analysis and argument) with verbatim quotes, each checked against the extracted PDF text via quote_check (all returned grounded: true).
No note in the retrieve-before-write list overlaps this paper's subject matter directly (the listed neighbors concern QFT/spacetime-divide philosophy of physics, Kepler/Ptolemy historical astronomy, and unrelated entities); see commentary below on the one genuinely thematic echo.
Claim: the WIMP (weakly interacting massive particle) remains the single most-mentioned and most-central dark-matter candidate across the literature, but its role connecting astrophysics and high-energy physics has sharply weakened since 2015
Using a frozen NASA Astrophysics Data System snapshot of 201,627 unique records (143,390 with arXiv classifications), indexed 21 May 2026 and restricted to publication years through 2025, the paper finds that astrophysics remains the larger field by aggregated primary classification throughout 2010–2025 (48.7% of classified papers in 2025, vs. 26.8% for high-energy physics), even though the single class hep-ph first overtakes the single class astro-ph.CO in 2015. Separately, in a concept co-occurrence network built from paper abstracts, the WIMP-related node (combining generic WIMP, neutralino, LSP, Higgsino, gravitino, and sneutrino mentions) stays the most central candidate by prevalence-weighted spectral centrality across the whole literature in both 2006–2015 and 2016–2025. But its normalized cross-field betweenness — how much it sits on the shortest paths connecting astrophysics-oriented and particle-physics-oriented concepts — falls from 0.073 in 2006–2015 to 0.031 in 2016–2025, and removing the WIMP node from the network cuts cross-field connectivity efficiency by 41.5% in the earlier period but only 6.2% in the later one (where Axion+ALP and primordial black holes now have larger removal effects). The paper's own gloss: WIMP-related research "remains central across the literature, even as cross-field connections become less concentrated around it" — i.e., it hasn't become a marginal topic, but it has stopped being the thing that ties the two fields' dark-matter literatures together.

Claim: the paper formalizes "discovering dark matter" as requiring four distinct, separately warrantable achievements, such that no single candidate result automatically delivers all four
The paper proposes that a strong dark-matter-discovery claim has the logical structure D = I(c) ∧ A(c) ∧ E(c) ∧ L(c,c,c), where constitutive identification (I) establishes what kind of particle, field, object, or population has been found; cosmic attribution (A) establishes that it has the abundance, persistence, and distribution required of the cosmic dark component; explanatory adequacy (E) establishes that it accounts for the relevant astronomical/cosmological phenomena; and cross-domain identification (L) is the additional warrant needed to treat the separately-characterized referents of I, A, and E as the same entity. The framework is explicitly candidate-neutral and is used to show that different successor programs could close different subsets of the four conditions: a laboratory axion/ALP signal could achieve constitutive identification while leaving cosmic attribution and cross-domain identification open; a sufficiently comprehensive primordial-black-hole population could achieve attribution and explanatory adequacy without identifying any new particle; and a successful modified-gravity theory could dissolve the need for a material dark component altogether rather than complete the chain.
source_quote: "Constitutive identification, 𝐼 (𝑐 𝐼 ), establishes what kind of particle, field, object, population, or physical structure has been identified. Cosmic attribution, 𝐴(𝑐 𝐴), establishes that a component or population has the abundance, persistence, and distribution required of the cosmic dark component. Explanatory adequacy, 𝐸 (𝑐 𝐸 ), establishes that the proposed explanation accounts for the relevant astronomical and cosmological phenomena at the required scales." source_quote_2: "A WIMP result could potentially connect all four only through convergent evidence. A laboratory axion or ALP signal leaves cosmic attribution and cross-domain identification open; a cosmologically significant PBH population could close the dark-matter problem without a new particle; and modified-gravity success may explain attributed phenomena while removing the need for a dark component." source_url: https://arxiv.org/pdf/2610.14137 source_title: "Diverging paths to dark-matter discovery" source_author: "Simon Allzén" source_venue: "arXiv:2610.14137 [physics.soc-ph]" source_date: 2026-10-09 source_tier: 1 source_sha: 080f5b42630605cd37f6e375bb1d43583dc596b512f1b85341ee79a18ef5c279
Claim: the WIMP functioned as an "evidential keystone" from the mid-1980s because it was the first candidate to make constitutive identification (what the particle is) and cosmic attribution (that it is the dark component) seem jointly attainable through convergent, independently-warranted evidence
The paper traces a specific lineage for why the WIMP acquired this coordinating role rather than treating "dark matter is a particle" as a default assumption: Gershtein and Zel'dovich (1966) used cosmological density bounds to constrain neutrino mass — the first step connecting a particle property to cosmic dynamics; Cowsik and McClelland (1973) then proposed massive neutrinos as the missing mass in clusters; Tremaine and Gunn (1979) derived a phase-space bound limiting ordinary neutrinos' capacity to constitute galactic halos; and Drukier/Stodolsky (1984) and Goodman/Witten (1985) supplied the detection methodology that let a terrestrial experiment target a galactic-halo candidate directly. Supersymmetric theories independently supplied stable weak-scale relics. The WIMP's distinctive promise, per the paper, was that no single one of these results was sufficient for discovery on its own — but their convergence could jointly warrant it.

I call this coordinating role that of an evidential keystone." source_url: https://arxiv.org/pdf/2610.14137 source_title: "Diverging paths to dark-matter discovery" source_author: "Simon Allzén" source_venue: "arXiv:2610.14137 [physics.soc-ph]" source_date: 2026-10-09 source_tier: 1 source_sha: 080f5b42630605cd37f6e375bb1d43583dc596b512f1b85341ee79a18ef5c279
Further leads
- The paper's own empirical finding that 13-family candidate-mention profiles show no increase in divergence between astrophysics and high-energy physics over time (mean Jensen–Shannon divergence 0.326 in 1995–2004 vs. 0.293 in 2016–2025) — a quantitative result, held back from claim status by the single-source cap. (arXiv:2610.14137, §4.)
- A fixed-seed audit of 500 multi-classified papers found 500/500 agreement between a paper's first-listed ADS class and its arXiv primary category (Wilson 95% CI 0.992–1.000), supporting the paper's primary-classification convention — a methodology-validation number, not independently corroborated this session. (arXiv:2610.14137, §3, §8.2.)
- Candidate-family prominence is asymmetric between fields: axion/supersymmetry families are relatively more prominent in high-energy physics, while PBHs, MACHOs, and ultralight/fuzzy candidates are relatively more prominent in astrophysics (Figure 2) — not developed into a claim this session.
- Allzén has an earlier, apparently closely related solo preprint, "Dark matter: Explanatory unification and historical continuity" (arXiv:2412.13404, 2024), cited by this paper as reference [42] — not independently fetched this session; likely the direct predecessor to this paper's framework.
- The 1985 IAU Symposium 117 ("Dark Matter in the Universe," Kormendy & Knapp eds., D. Reidel, 1987) proceedings contain a direct quote from Jim Peebles ("New ideas from particle physics have greatly stimulated some old speculations in cosmology...") and from Scott Tremaine distinguishing baryonic from non-baryonic dark matter, both reproduced in this paper (citing Tremaine's contribution to that volume, ref. [45]) — currently sourced only via Allzén's secondary quoting; the original symposium proceedings were not independently fetched this session and would be needed before either quote could ground a claim about Peebles's or Tremaine's own 1980s views.

- The paper distinguishes particle physics's 5σ discovery convention from astronomical/cosmological attribution standards (consistency across observations, population inferences, and physical scales), citing Cowan 2022 (Review of Particle Physics statistics chapter), Franklin 2013, and Dorigo 2015 — not independently checked this session.
