BDT as a Surrogate Model / Corpe, Louie Dartmoor (speaker) (Laboratoire de Physique Clermont Auvergne (LPCA)) ; Haddad, Abdelhamid (speaker) (Laboratoire de Physique de Clermont-Auvergne (LPCA))
I will present the reinterpretation material of the CalRatio + X ATLAS analysis (arXiv:2407.09183). The analysis focuses on neutral long-lived particles decaying within the ATLAS hadronic calorimeter. [...]

Introduction to the Virtual Research Environment: an end-user perspective / Sinha, Sukanya (speaker) (The University of Manchester (GB))
One of the objectives of the EOSC (European Open Science Cloud) Future Project was to integrate diverse analysis workflows from Cosmology, Astrophysics and High Energy Physics in a common framework. This led to the inception of the Virtual Research Environment (VRE) at CERN, a prototype platform supporting the goals of Dark Matter and Extreme Universe Science Projects in compliance with FAIR (Findable, Accessible, Interoperable, Reusable) data policies.

Open Event Generation / Marshall, Zach (speaker) (Lawrence Berkeley National Lab. (US))
This contribution will describe ongoing efforts to provide event generation output to the broader community. There are a number of advantages that such a project could offer: reduced waste, easier project uptake, better validation, and improved communication between the experimental and phenomenological communities, among others..

WorkspaceExplorer: Web-based visualisation of full likelihoods / Austrup, Volker Andreas (speaker) (The University of Manchester (GB))
In recent years, LHC experiments are increasingly publishing the full likelihood models for statistical analysis in HEPData. For the purporse of reproducing and reinterpreting such analyses, it is essential to understand the contents of these statistical workspaces. [...]

Profile Likelihoods on ML-Steroids / Schmal, Nikita (speaker)
Global SMEFT analyses combine a vast range of LHC measurements to construct likelihoods to put constraints on physics beyond the Standard Model. However, constructing and evaluating profile likelihoods for such analyses is computationally intensive and prone to instability and noise. [...]

HS³ / Burgard, Carsten (speaker) (Technische Universitaet Dortmund (DE))
The complexity of modern high-energy physics (HEP) experiments demands robust, flexible, and interoperable tools for statistical modeling. The HEP Statistics Serialization Standard (HS³) addresses this need by providing a unified framework for serializing statistical models and datasets in HEP research that allows to seamlessly switch between different implementations and modeling frameworks.

Data Reuse for MC Tuning and Validation / Meinzinger, Peter (speaker) (Zürich University)
For the development of modern event generators, the comparison to data is an invaluable tool for the tuning and validation of the code. I will review efforts where the comparisons to data from past colliders have allowed for improvements and extensions of event generators, with an emphasis on photoproduction and hard diffraction at HERA..

Research use of event-level open data - how to get there / Lassila-Perini, Kati (speaker) (Helsinki Institute of Physics (FI))
As agreed in the CERN Open Data policy, all LHC experiments are committed to releasing research-quality open data. CMS has pioneered this effort and now celebrates a decade of regular data releases, with all LHC Run 1 data available in the public domain and ongoing releases of Run 2 data. [...]

Dark Matter from Anomaly Cancellation / Debnath, Hridoy (speaker)
We discuss a class of theories that predict a fermionic dark matter candidate from gauge anomaly cancellation. As an explicit example, we study the predictions in theories where the global symmetry associated with baryon number is promoted to a local gauge symmetry. [...]
