        Light-by-light scattering and dilepton production in ultra-peripheral heavy-ion collisions with ATLAS 1h 30m

        Abstract:

        The presence of a large flux of photons accompanying relativistic heavy
        ion beams leads to a significant number of photon-induced processes,
        including photon-photon fusion. These processes are remarkably clean
        with little or no remnant activity from the interacting particles. I
        will present the status of photon-photon fusion measurements resulting
        in either two photons (γγ→γγ) or two charged leptons (γγ→l+l−) in
        the final state, measured by the ATLAS experiment in ultra-peripheral
        heavy-ion collisions.
