Theoretical and Experimental Constraints in the $\mu$--$\tau$ Four-Lepton Sector of the SMEFT: implications to neutrino self interactions

Aadarsh Singh, G. D'Ambrosio, Sudhir K. Vempati · 2026

We study the dimension-six SMEFT four-lepton operators in the $\mu$--$\tau$ sector. These operators control both charged-lepton scattering and neutrino self-interactions, the latter being weakly const…

Incorporating the underuse problem in the tragedy of the commons

Shota Shibasaki, Wakaba Tateishi, Shuhei Fujii, Ryosuke Nakadai · 2026

The tragedy of the commons has traditionally been framed as a problem of resource overuse driven by self-interested exploitation. In contrast, growing empirical evidence shows that insufficient use or…

CuLifter: Lifting GPU Binaries to Typed IR

Jisheng Zhao, Huanzhi Pu, Shinnung Jeong, Chihyo Ahn, Hyesoon Kim · 2026

GPU compilers merge all data types into a single unified register file, erasing the type information that binary-analysis tools rely on. We show that type recovery from this untyped register file is t…

Beyond Code Reasoning: A Specification-Anchored Audit Framework for Expert-Augmented Security Verification

Masato Kamba, Hirotake Murakami, Akiyoshi Sannai · 2026

Security-critical software is routinely audited by tools that reason about vulnerabilities as repository-local code patterns. Yet specification-governed systems -- protocol stacks, consensus implement…
