  1. 30. Prospects for the ILC project
    Yasuhiro Okada (KEK)
    21/06/2021 10:00

    The International Linear Collider (ILC) is the highest-energy electron-positron collider proposed by the international high-energy physics community. It is planned to start as a Higgs Factory with center-of–mass energy of 250 GeV, keeping energy extendibility at a later stage. Preparation for the ILC has entered a new stage recently with publication of “Proposal for the ILC Preparation...

  3. 40. Terazooming into compositeness/ALP's
    Dr ABHISHEK IYER (IP2I Lyon)

    The Tera-Z phase of future e+e− colliders, FCC-ee and CepC, is a goldmine for exploring Z portal physics. We focus on axion-like particles (ALPs) that can be produced via Z decays with a monochromatic photon. As a template model, we consider composite Higgs models with a light pseudo-scalar that couples through the Wess-Zumino-Witten term to the electroweak gauge bosons. For both photophilic...

  4. 35. New Physics prospects from D to pi l+l-
    Aoife Bharucha (CPT, Marseille)
    22/06/2021 10:00

    I will discuss the decay D to pi l+l-, providing motivation from the B physics anomalies. After having reviewed the previous status of the calculation for this decay, I will motivate our calculation where we take a new approach to the the resonance contributions and include for the first time the relatively large contributions from the weak annihilation diagrams. I will then discuss the...

  6. 41. On the EFT description of ALPs coupled to heavy chiral matter
    Quentin Bonnefoy
    22/06/2021 12:00

    The impact of heavy new physics on low-energy observables is generically and conveniently described using effective field theories (EFTs). The latter framework, when applied to the degrees of freedom of the standard model (SM), raises several questions, for instance: which is the most general EFT? which UV models require that the most general EFT be used? which observables allow to test...

  7. 39. The neutrinoless beta beta process at the LHC and beyond
    Richard Ruiz (Institute of Nuclear Physics (IFJ) PAN)
    22/06/2021 14:00

    The Majorana nature of neutrinos and whether lepton number symmetry is conserved are among the most pressing mysteries in physics today. This follows from their widespread implications for cosmology, nuclear physics, and particle physics. Along these lines, searches for the neutrinoless beta beta (0vBB) decay mode of heavy nuclei are highly sensitive probes of these questions, albeit with...

  9. 28. Naturalness, the deus-ex-machina of the muon g-2 anomaly and lepton non-universality.
    Francesco Sannino (CP3)

    g-2

    I will critically present the state-of-the-art of the observed standard model anomalies in flavor physics and in muon g-2 experiment. I will discuss whether the standard model could still be rescued both theoretically and experimentally and whether the anomalies can be considered as serious hints of new physics and what type. In particular I will make the case that the anomalies, especially...

  12. 32. A new resolution of flavor problem in 2HDM with U(1) Higgs gauge symmetry
    Pyungwon Ko (KIAS)
    24/06/2021 11:00

    Generic 2HDM's suffer from neutral Higgs mediated FCNC problem. Traditionally this problem is avoided by softly broken Z2 symmetry that distinguishes H1 and H2. In this talk I implement the softly broken Z2 symmetry to spontanesouly broken U(1) Higgs gauge symmetry. In this setup one often has to add new chiral fermions in order to maintain gauge anomaly cancellation. I discuss extensions of...

  13. 34. Towards the Consistent Dark Matter exploration
    Alexander Belyaev (Southampton University)
    24/06/2021 14:00

    The nature of Dark Matter (DM) is one of the greatest puzzles of modern
    particle physics and cosmology. Although overwhelming observational
    evidences from galactic to cosmological scales point to the existence of
    DM, after decades of experimental effort only its gravitational
    interaction has been experimentally confirmed. Currently, we do not have
    any clue on DM properties, such as...
