  24. 5. Collider Consequences of Baryogenesis and Dark Matter from B Mesons
    Miguel Escudero (IFIC-University of Valencia)

    In this talk based on ArXiv:1810.00880, I will detail what are the different approaches by which current collider experiments can test whether Baryogenesis and Dark Matter arise from CP violating B meson oscillations and their subsequent decays in the early Universe. These are:

    1) Searches for heavy colored scalars (ATLAS, CMS).
    2) Measurements of direct CPV in the B meson system (LHCb,...

  25. 2. Novel $B$-decay signatures of light scalars at high energy facilities
    Maria Ramos (LIP)

    In this talk, we will discuss the phenomenology of light scalars of masses $m_1$ and $m_2$ coupling to heavy flavour-violating vector bosons of mass $m_V \sim $ TeV. This scenario is particularly motivated, as the scalar-vector coupling arises naturally in non-minimal composite Higgs models and the vector boson is a prime candidate to solve the apparent anomalies observed in tests of lepton...

  26. 4. Probing dark sectors with long-lived particles at BELLE II
    Ruth Schäfer

    I will present a new search for light scalar singlets in rare meson decays. For tiny interactions, the scalar is long-lived at detector scales and decays into displaced pairs of leptons or light mesons. I will show that Belle II has a remarkable potential to probe scalars in the GeV range with couplings as small as $10^{−5}$. The predicted sensitivity is higher than at the long-baseline...

    Jonathan Plews (University of Birmingham (GB))
  28. 3. Soft displaced objects from dark matter at the LHC
    Susanne Westhoff (Heidelberg University)

    Feebly interacting dark sectors with a compressed spectrum should leave characteristic signatures with soft displaced particles in the LHC detectors. I will discuss how we can directly predict such signatures from co-scattering dark matter in the early universe. At ATLAS and CMS searches for soft displaced objects are underway, but limited by large hadronic background. Can LHCb do better?
