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. [...]

Exploring Career Pathways: Insights about career development and networking / Gallo, Maria (speaker) ; Alekou, Androula (speaker) ; Biedermann, Andrea (speaker)
Link: https://alumni.cern/news/1804220 Topics explored: • How can I apply the growth mindset to the career application process and my career planning? • In what ways can I identify my key transferable skills and competences? • How can I navigate a career pivot? What if I am climbing the ladder and discover the ladder is leaning on the wrong wall? • What does self-value look like for high achievers? • How can I make career decisions that factor in holistic living and quality of life? • What is the value of career stories? (And why are career stories more powerful than advice?) • Why should I embrace uncertainty, curiosity and stepping out of my comfort zone?

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.

Ultra-high energy astroparticle physics: latest results and future prospects / Castellina, Antonella (speaker) (INFN Torino)
Abstract: In this talk, I will give an overview of the most recent experimental results on cosmic rays and multi-messengers in the ultra-high energy range. I will highlight the outcomes from the world's largest cosmic ray experiment, the Pierre Auger Observatory, and discuss the global coherent view they provide, which appears to be much more complex than previously thought [...]

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. [...]
