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,...

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...

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...

18. Search for the true muonium at LHCb

Jonathan Plews (University of Birmingham (GB))

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?
