Reconstruction: A Blind Benchmark for Recovering Research Ideas from Pre-Publication Bibliographies

Shaolong Chen, Yanlin Fei, Nazhou Liu +6

Can a language model recover the true research idea of a published paper when given only that paper's pre-publication bibliography? We introduce Reconstruction, a blind idea-recove…

First measurements of the branching fractions of $J / ψ$ and $ψ (3686) \to Σ^{0} Σ ˉ^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ and $(2712 \pm 14) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the hadronic decays $J/ψ\to…

How Do Agents Fail on AutoResearch: End-to-End Diagnostic Evaluation on 100 Real-World Frontier Research Tasks

Yanlin Fei, Nazhou Liu, Xinmiao Yu +6

AI has long assisted scientific research, but the rapid advance of LLMs and agentic scaffolds is reshaping the landscape; a single system can now carry whole-stage research from an…
