  1. 19. Quantum information observables at ATLAS
    Ondrej Penc (CERN)
    11/09/2026, 14:00

    This talk will cover the quantum-information observables that can be measured with the ATLAS experiment at the LHC. After a short introduction to the relevant concepts, I will discuss current measurements and present the most recent results. Finally, I will introduce a future measurement in which our institute is involved.

  2. 7. Search for QCD instantons in proton–proton collisions at ATLAS using inner detector and ALFA data

    QCD instantons are non-perturbative, semiclassical solutions of the Yang–Mills equations that connect topologically distinct vacua and encode tunneling between them. They underlie key phenomena such as axial U(1)U(1)U(1) symmetry breaking, anomalous chirality violation via the axial anomaly, and contribute to the structure of the QCD vacuum and chiral symmetry breaking. Their observation would...

  3. 6. Signal Generator for Instanton-Induced Processes in Proton-Proton Collisions
    Vojtěch Loubal
    11/09/2026, 14:36

    QCD instantons are non-perturbative, topological gluon-field configurations that mediate chirality-violating processes whose experimental signature is an isotropic, flavour-democratic, high-multiplicity final state, absent from the perturbative expansion and so far unobserved. We present a new Monte Carlo generator for QCD instanton-induced processes in proton–proton collisions, filling a gap...

  4. 27. Search for Axion-Like-Particles using di-photon signature with the ATLAS Forward Proton Detector
    Viktoriia Lysenko (Czech Technical University in Prague (CZ))
    11/09/2026, 14:47

    The search for an Axion-like particle in light-by-light scattering in Run-3 LHC data using the central ATLAS detector for di-photon signature and ATLAS Forward Proton (AFP) detector for a scattered forward proton signature is presented together with the operational and data quality challenges for the AFP detector.
