Elliptic flow of mesons in CuAu collisions at GeV and UU at GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +379

The second-order azimuthal anisotropy coefficients () of neutral mesons () have been measured as a function of the transverse momentum () and centrality of Cu…

Learning Self-Interpretation from Interpretability Artifacts: Training Lightweight Adapters on Vector-Label Pairs

Keenan Pepper, Alex McKenzie, Florin Pop +6

Self-interpretation methods prompt language models to describe their own internal states, but remain unreliable due to hyperparameter sensitivity. We show that training lightweight…

Endogenous Resistance to Activation Steering in Language Models

Alex McKenzie, Keenan Pepper, Stijn Servaes +6

Large language models can recover mid-generation from task-misaligned activation steering, producing explicit verbal restarts (e.g., ``wait, that's not right'') and continuing on-t…

Transverse single-spin asymmetry of forward mesons in collisions at GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +380

Utilizing the 2012 transversely polarized proton data from the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, the forward -meson transverse single-spin asymm…

MAEBE: Multi-Agent Emergent Behavior Framework

Sinem Erisken, Timothy Gothard, Martin Leitgab +1

Traditional AI safety evaluations on isolated LLMs are insufficient as multi-agent AI ensembles become prevalent, introducing novel emergent risks. This paper introduces the Multi-…

Cross sections of mesons in collisions at forward rapidity at GeV and central rapidity at GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +497

We present the first measurements of the forward and midrapidity -meson cross sections from collisions at and ~GeV, respectively. We also report th…
