      AI Workfest Session 2 Lecture Theatre 466 (Gilbert Scott Building)

      Lecture Theatre 466

      Gilbert Scott Building

      The AI Workfest will address three complementary themes: the breadth of AI efforts already underway within the collaboration, as highlighted during the AI Town Hall on July 16; the development of an ePIC AI policy; and global AI initiatives and the opportunities they may offer ePIC.

      We will also provide an overview of global AI initiatives, such as the Genesis Mission, and discuss their relevance to ePIC. In particular, we will connect the vision behind these initiatives with ePIC’s streaming computing model and the goal of seamless data processing from detector readout through analysis.

      The discussion of the ePIC AI policy will focus on how AI is changing the way we work, including areas such as software development and scientific writing.

        • Instanton processes at the EIC/ePIC 20m

          Tomáš Sýkora, Institute of Particle and Nuclear Physics, Charles University
          Beyond its precision parton-structure program, ePIC's high inclusive luminosity, 4π hermeticity, and particle identification give direct access to non-perturbative and topological QCD processes in the final state. We develop one such case in detail with dedicated simulation and outline a second as a motivated future measurement.
          The primary case is instanton-induced DIS — a chirality-violating, flavour-democratic process absent in perturbation theory. Using InstGen, a semiclassical instanton event generator whose deep-inelastic line we have adapted to ePIC's asymmetric beams (9 GeV e⁻ × 275 GeV p), we perform generator- and hadron-level studies with Pythia 8. At √s ≈ 100 GeV the accessible events are predominantly low-mass; the classic high-mass "fireball" is strongly rate-suppressed, and higher-energy running extends kinematic reach but does not recover it. The discriminating signatures nonetheless survive hadronization and separate cleanly from a perturbative baseline: enhanced strangeness (≈ 2×), high rest-frame isotropy (sphericity ≈ 0.6 vs ≈ 0.1), and elevated multiplicity. ePIC's luminosity and PID thus make it a precision instrument for characterizing this low-mass instanton regime rather than for high-mass discovery, with the trustworthy observables being shapes and flavour ratios rather than absolute rates.
          We additionally note the baryon junction — a proposed gluonic, topological carrier of baryon number — as a complementary target whose clean observables (a slow, Regge-like net-baryon stopping slope, net-baryon/net-charge decoupling, and A-dependence) are well matched to ePIC's forward tagging and low-momentum baryon identification. As no current generator implements the junction mechanism, we present this as a measurement motivation and identify the simulation development it would require.

        • The Carbon Footprint of the Electron-Ion Collider 15m

          The Electron-Ion Collider (EIC) will be the first collider built in the 21st century — an era where climate change cannot be ignored. Throughout its construction, operation, and scientific lifestyle, the EIC will contribute significant carbon emissions to the atmosphere. These emissions do not outweigh the importance of the science that will be done by the collaboration, but it is crucial to limit them as much as possible. We introduce a comprehensive assessment of the EIC’s emission factors, including the materials and performance of the accelerator complex itself, as well as the computation and travel required by the EIC’s scientific community. The framework for the survey and preliminary emission estimates will be presented, with special emphasis placed on the largest emission sources. Identifying these hotspots, especially early in the EIC’s lifespan, allows us to suggest better sustainability practices for the facility and advocate for more environmentally conscious choices for the broader physics community.

        • Digitalizing DIS in Lean 4: A machine-provable basis for AI research at the EIC 15m

          An OpenAI model has disproved a central conjecture in discrete geometry [OpenAI, May 2026].” Such headlines from the field of mathematics are increasingly common and reflect a comprehensive effort to “formalize” or “digitalize” [*] mathematics via machine-readable and machine-verifiable proofs, which allows AI models to generate new theorems with their proofs. One of the platforms used is the functional programming language Lean 4 whose dependent type system is used to build up rigorously provable lemmas and theorems. Building on the solid mathematical basis, physicists have been “digitalizing” physics concepts and relationships from classical mechanics up to quantum field theory as part of the PhysLib project. More recently, we have been expanding on this with electron-proton scattering formalisms, DIS kinematics, parton distribution functions, structure functions, and form factors, and their connections to experimental observables. Providing this formally verified foundation creates an un-hallucinable mathematical guardrail for AI agents and allows the EIC community to deploy next-generation AI tools for automated discoveries and robust extractions that are mathematically guaranteed to respect physical laws.

        • Quality Assurance for the EEEMCal Long-Lead PbWO₄ Crystal Procurement 15m

          The ePIC Backward Electromagnetic Calorimeter will use PbWO₄ (PWO) crystals as the radiator material for precision electromagnetic calorimetry in the electron endcap. The PWO is a CD3-A and CD3-B long-lead item. A total of 1069 crystals were received under CD3-A and the first batches of CD3-B crystals have started arriving. This talk will present the results of the current status of PWO crystal QA and discuss the receiving quality assurance process developed for the EEEMCal PWO long-lead procurement. This will include a practical overview of our product quality, individual quality control plans, and component inspection and test plans, and how we implement them.

        • NPS Prototype beam test with streaming readout and AI/ML-based clustering algorithms in HallC, JLab 15m

          Future experiments at Jefferson Lab (JLab) and the Electron-Ion Collider (EIC) are designed to leverage the highest achievable luminosities to probe hadronic structure with unprecedented precision. These measurements require the efficient identification of rare physics events in the presence of substantial backgrounds. In this work, measurements of meson structure functions through the Sullivan process serve as the physics-validation case for developing and evaluating AI/ML processing within a streaming-readout environment.

          To validate the approach, existing data from Jefferson Lab (Jlab) acquired with the Neutral Particle Spectrometer, a PWO based electromagnetic calorimeter were used. Transformer-based and graph neural network (GNN) models were trained for cluster reconstruction and anomaly detection using existing meson data. These models have been integrated into the JANA2 reconstruction framework which enables GPU-accelerated inference. In parallel, a separate neural-network model has been implemented on an FPGA to filter background events. This completed work establishes the heterogeneous CPU, GPU, and FPGA processing chain needed for real-time reconstruction and event selection.

          The next step will be a rate capability test using a beam test at JLab using the small-scale NPS prototype electro-magnetic calorimeter. JLab FADC250 and VXS Trigger Processor (VTP) modules will provide the bandwidth required for streaming readout. This beam test will provide an
          estimation of achievable throughput and latency for the streaming-readout system while evaluating the applicability of the AI/ML-based models under realistic experimental conditions.

        • Multi-Scale Background Rejection and Physics Process Discrimination in Electron-Ion Collider Experiments Using Machine Learning 15m

          At the Electron-Ion Collider, the reliable identification of physics processes of interest demands robust strategies for suppressing instrumental backgrounds and for resolving distinct reaction types within complex, high-multiplicity event environments.In the context of streaming readout architectures, data-driven machine learning approaches offer an automated pathway to event selection and physics discrimination.
          We present a machine learning framework that operates at two complementary levels of detector granularity: anomaly identification within tracker hit collections across multiple detector subsystems, and classification of physics reaction types at the event level using calorimeter and tracking observables. The framework ingests reconstructed detector responses across a hierarchy of observables - from low-level geometric and kinematic track parameters to higher-order event-level quantities while constructing feature representations informed by the underlying physics and tailored to distinguish signal-like reactions from process-level backgrounds. The choice of observables is motivated by generalizability both across heterogeneous detector technologies comprising the ePIC detector and across the range of physics processes accessible at the EIC. Building upon our prior work employing complementary unsupervised methods for hit-level anomaly characterization, we introduce a classification approach for event-level discrimination between inclusive deep inelastic scattering and process-specific reactions, trained on mixed datasets. The approach targets a hierarchy of discrimination objectives: identification of noise at the sub-event level, and the dominant physics reaction at the event level, yielding interpretable outputs for both background characterization and physics process tagging.
          The present study constitutes a proof-of-concept demonstration, and lays the groundwork for a scalable, multi-method framework for automated physics discrimination at the EIC, with the present prototype intended as a foundation for expansion toward a unified ensemble methodology as datasets and detector commissioning mature.
