  6. 27. Experiment 320 experience with Acts planar geometry tracking
    Roman Urmanov (Weizmann Institute of Science (IL))
    21/04/2026, 09:25

    The SLAC Experiment 320 collides 10 TW laser pulses with a high-quality 10 GeV electron beam from the FACET-II RF LINAC. This configuration is expected to produce e⁺e⁻ pairs via the nonlinear Breit–Wheeler process in the strong-field tunneling regime, with an estimated yield of 0.01–0.1 pairs per collision. Such a small signal rate is accompanied by substantial backgrounds originating, for...

  7. 28. ACTS at the proposed Lohengrin experiment in Bonn
    Cedric Carl Breuning (Universität Bonn)
    21/04/2026, 09:45

    The proposed Lohengrin experiment will search for light dark matter at the Electron Stretcher Accelerator (ELSA) in Bonn. It employs the fixed-target missing momentum based technique for searching for dark-sector particles. A beam of electrons is extracted from ELSA and is shot onto a thin target to produce mainly Standard Model bremsstrahlung and – in rare occasions – possibly new...

  10. 25. Integration of new Graph Based Seeding Algorithm in ACTS
    Jasper Preston (University of London (GB))
    21/04/2026, 11:10

    Over the last few years, ACTS has made substantial progress toward a detector-independent software toolkit for charged-particle tracking. Looking ahead to future experiments (most notably the Phase-II upgrade of the ATLAS detector) the much higher hit occupancies and track densities will demand seeding algorithms that are both more efficient, more selective and faster. This contribution...

    Carlo Varni (AGH University of Krakow (PL))
    23/04/2026, 11:05

    Charged particle track reconstruction is among the most computationally expensive tasks in event reconstruction in high-energy physics experiments. A major contribution to this cost arises from the track seeding stage, which provides the initial candidates for subsequent track fitting algorithms. Track seeding is particularly sensitive to combinatorial effects, and in the high-occupancy...

  26. 26. GUNTAM: A Transformer for seed reconstruction
    Corentin Allaire (IJCLab, Université Paris-Saclay, CNRS/IN2P3)
    23/04/2026, 11:35

    Reconstructing particle trajectories is a significant challenge in most particle physics experiments and a major consumer of CPU resources. In classical tracking, most of the intensive computational workload stems from the seed identification process, while track finding is well understood.
    To address the complexity of seed reconstruction, we introduce GUNTAM, a transformer-based algorithm...

  27. 1. Large Impact Parameter Track Reconstruction in ATLAS Using ACTS (25+10)
    Jackson Carl Burzynski (University of Oklahoma (US))
    23/04/2026, 16:00

    Searches for long-lived particles in ATLAS require efficient reconstruction of charged-particle tracks with large transverse impact parameters, which generally fall outside the acceptance of standard tracking configurations. To address this, ATLAS employs a secondary tracking pass known as Large-Radius Tracking (LRT), which reconstructs tracks using hits not assigned in the primary tracking...
