    Talk

    Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum. The implementation of semi-visible jets is done using the Pythia Hidden valley module to duplicate the dark sector showering. In this work, several jet substructure observables have been examined to compare...

  4. 4. Casting a GraphNet to catch dark showers (8'+2')
    Elias Bernreuther (RWTH Aachen University)

    Talk

    Strongly interacting dark sectors predict dark showers, which give rise to novel LHC signatures such as semi-visible jets. However, these are difficult to search for with conventional analysis techniques. In my talk I will first consider the sensitivity of existing and prospective LHC searches to semi-visible jets and then discuss how deep learning can help to distinguish dark showers from...

  5. 40. Dark photons from hadronic showers (8'+2')
    Luc Jean Marie Darmé (INFN - National Institute for Nuclear Physics)

    Talk

    Neutral mesons decay is often considered the dominant production mechanism for light dark photons in proton-proton and proton-nucleus collision. However, the produced hadronic showers also transfer a relevant amount of their energies into electromagnetic subshowers. We show that in certain cases, the positrons created in these sub-showers can lead to dark photon production rates significantly...

  6. 8. Probing the real triplet scalar dark matter at colliders (8'+2')
    Yong Du (University of Massachusetts-Amherst)

    Talk

    We study discovery prospects of the real triplet model at the LHC and a future 100TeV $pp$ collider. The model provides a dark matter candidate and its smoking-gun signature is the so-called "disappearing charged tracks". We recast current 13TeV LHC searches for disappearing tracks and find that the LHC presently excludes a real triplet scalar lighter than 287GeV with...
