Analysis

The article promotes a RAG-less approach using long-context LLMs, suggesting a shift towards self-contained reasoning architectures. While intriguing, the claims of completely bypassing RAG might be an oversimplification, as external knowledge integration remains vital for many real-world applications. The 'Sage of Mevic' prompt engineering approach requires further scrutiny to assess its generalizability and scalability.

ArXiv

Analysis

This paper explores the potential of the FASER experiment to detect compressed Higgsinos, a specific type of supersymmetric particle predicted by the MSSM. The focus is on scenarios where the mass difference between the neutralino and the lightest neutralino is very small, making them difficult to detect with standard LHC detectors. The paper argues that FASER, a far-forward detector at the LHC, can provide complementary coverage to existing search strategies, particularly in a region of parameter space that is otherwise challenging to probe.
