LHCpublications
This repository holds three things that are easy to confuse, so they are named separately below: the corpus, the indexed subset, and the benchmark.
| Role | What it is | Files |
|---|---|---|
| Corpus | every paper we collected and converted (curated) | corpus_manifest.jsonl, ATLAS.json, CMS.json, arxiv/, failed_*.csv, removed_papers.json, excluded_records.json |
| Indexed subset | the 96 papers that the retrieval index is built over | indexes/ |
| Benchmark | 100 questions written over the indexed subset | benchmark.jsonl |
The corpus
Collected from INSPIRE and converted from the arXiv sources:
| Source | Metadata records | With arXiv id | Without arXiv id |
|---|---|---|---|
| ATLAS | 1,677 | 1,560 | 117 |
| CMS | 1,912 | 1,633 | 279 |
| Total | 3,589 | 3,193 | 396 |
57 ATLAS records that referred only to the astronomy papers described under
Known composition issues were moved to excluded_records.json during
curation, which is why the ATLAS row is smaller than the 1,734 records
originally fetched.
The 3,193 records that carry at least one identifier refer to 2,338 distinct
papers, and all of them are present in the corpus. The 396 records without an
identifier are listed in failed_ATLAS.csv and failed_CMS.csv (columns
Title, DOI, arXiv, with the last one empty) rather than dropped silently;
they are records with no arXiv source to download, which is not an extraction
failure.
arxiv/ holds 2,771 converted papers as markdown, one directory each, with
<id>.md, <id>.pdf and figure files. That is 2,338 papers from the metadata
lists plus 433 further documents that the same corpus collection returned —
mainly conference proceedings, notes and early detector papers.
corpus_manifest.jsonl lists every paper in the corpus (2,771 rows, one per
paper) with its INSPIRE title, collaborations, document type and year, plus flags
recording whether the paper appears in ATLAS.json or CMS.json and whether an
INSPIRE record was found at all. Use it to enumerate the corpus without walking

Known composition issues
- Removed during curation (62 papers). 58 papers of the Herschel-ATLAS
astronomy survey, which share the name "ATLAS" and were returned by the same
collection, and four documents unrelated to the LHC:
1310.6807(a galaxy-ring paper),1711.04330(a black-hole X-ray binary),2501.08313(an LLM technical report) and2309.11285(an NLP shared-task overview). Every removed paper is listed with its reason inremoved_papers.json, and the 57 INSPIRE records that referred only to them are kept inexcluded_records.json, so the removal is auditable rather than silent. - One paper is stored in a single directory at its latest version
(
2506.05018v2); the earlier version directory was removed. - 58 papers are LHC sub-detector papers whose INSPIRE records carry a group name
instead of the plain collaboration (
CMS Tracker,CMS HCAL,ATLAS TDAQ,ATLAS Forward Detectors, ...). They are part of the corpus. - The 96-paper indexed subset used in the paper contains none of the removed papers. Every paper cited as benchmark evidence is inside that subset.
- Old-style identifiers are stored with an underscore, e.g.
hep-ex_0007045forhep-ex/0007045.
Rebuild or re-fetch arxiv/ with
benchmarks/LHCpubs_run2/scripts/build_corpus.py from the code repository.
The indexed subset
The retrieval index is built over a fixed 96-paper subset of the corpus, listed
in corpus_papers.json in the code repository. indexes/ contains the graph and
vector index over that subset: 4,772 chunks, 24,909 entities and 61,874 relations,
with 512-token chunks and 50-token overlap. Chunk, entity and relation counts
anywhere in the paper describe this subset, not the full corpus.
The benchmark: benchmark.jsonl
100 questions over the indexed subset, 25 per genotype. Every question requires
evidence from at least two papers, so it cannot be answered by a single retrieval
call over one document. The file was named benchmark_100.jsonl in earlier
revisions.

benchmark, benchmark_role, gate_pass |

Genotypes
25 questions per genotype:
| Id | Genotype | What it requires |
|---|---|---|
| T1 | complementary bridge | one paper supplies a value or entity that the other names but does not resolve; neither paper alone answers the question |
| T2 | cross-document aggregation | the same measured quantity reported in two or more papers, which must be collected and compared |
| T3 | heterogeneous multi-hop | hops that genuinely need different retrieval strategies (a verbatim detail, an entity-centred hop, an aggregate) |
| T4 | three-retriever | a concrete numeric or verbatim value plus two further hops of a different kind |
The ids were renumbered from an earlier seven-type generation taxonomy, in which these four were numbered T3/T4/T5/T7. If you are matching against an older revision of the paper, T1/T2/T3/T4 here correspond to T3/T4/T5/T7 there.
Retrievability gate
Every question passed a partial corpus-level reachability check before release: for each gold evidence item of at least 40 normalized characters, the first 80 characters starting one quarter of the way in must occur in a vector top-20 chunk, or the cited paper id must appear in the metadata of a top-20 chunk. A question is kept when at least half of its eligible evidence items are hits. The gate does not require one query to retrieve every supporting item. The question generation pools and the composer log that produced this file ship with the code repository, so the composition can be recomputed.
