Lighting up the Dark on the Quantum Tabletop / Ellis, Sebastian (speaker) (Universite de Geneve (CH))
Several open questions in particle physics could be addressed through the observation of extremely weakly coupled signals. In this talk, we will explore how tabletop(-ish) experiments operating at or near the so-called "quantum limit" can search for such signals. [...]

Challenges in high-precision determinations of CKM matrix elements using lattice QCD / Portelli, Antonin (speaker) (The University of Edinburgh)
The current precision on determining CKM matrix elements is below a per cent in several cases, and tensions between results are present, for example, in the Vus/Vud plane. Investigating that problem is essential for searching for new physics through weak decays [...]

Fermion-Monopole Scattering and Generalized Symmetries / Van Beest, Marieke (speaker)
I will discuss the problem of electrically charged, massless fermions scattering off magnetic monopoles. The interpretation of the outgoing states has long been a puzzle, as they can carry fractional quantum numbers. [...]

Conformal multi-Regge theory / Goncalves, Vasco (speaker) (Porto U.)
We propose and explore the Regge limit for correlation functions of five local primary operators in conformal field theories. After reviewing some features of Regge theory for flat-space scattering amplitudes, we analyse the analytic structure of conformal blocks both in position and Mellin space in the Regge limit and propose an extension of conformal Regge theory for five-point functions. [...]

Multi-scale cross-attention transformer encoder for event classification / Nojiri, Mihoko (speaker) (Theory Center, IPNS, KEK)
We deploy an advanced Machine Learning (ML) environment, leveraging a multi-scale cross-attention encoder for event classification, taking gg→H→hh→bbbb process at the High Luminosity Large Hadron Collider (HL-LHC) as an example. In the boosted Higgs regime, the final state consists of two fat jets. [...]
