Test of lepton flavor universality with and decays at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +494

We test lepton flavor universality with a measurement of the branching-fraction ratios $R(D^{(*)}) \equiv \mathcal{B}(\bar{B} \rightarrow D^{(*)} τ^{-} \barν_τ)/\mathcal{B}(\bar{B}…

Search for the decay

Belle, Belle II Collaborations, : +432

We present the first search for decays. We look for signal decays in events produced in asymmetric-energy electron-positron collisions. T…

Search for axion-like particles decaying to two photons at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +450

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…

Agentic AI for Gravitational Wave Data Analysis: A Head-to-Head Comparison of Coding Agents Executing a Matched Filter Pipeline on Einstein Telescope Simulated Data

Gianluca Inguglia

We report a methodological study of agentic AI in gravitational-wave data analysis: two systems, Claude Code (Anthropic) and Codex (OpenAI), autonomously executed the same simple e…

Search for the decay using data from the Belle and Belle II experiments

Belle, Belle II Collaborations, : +435

We report a search for the rare decay using mesons produced near threshold in electron-positron collisions and colle…

Study of decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay . This work presents the first result using Belle~II data, an updated Belle me…

A search for feebly-interacting particles in decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle , produced in and decays, where , $…
