  1. 101. Thermodynamics from the S-matrix reloaded
    Dr Pietro Baratella (IJS)

    Parallel Session Talk

    Over the past decade and more, S-matrix-based calculational methods have experienced a resurgence, proving to be both an elegant and powerful tool for extracting physical quantities without the need for an underlying Lagrangian formulation. In this seminar I will critically review the formalism introduced by Dashen, Ma, and Bernstein, which connects the thermodynamics of relativistic systems...

  2. 15. Hadronic vacuum polarisation contribution to the muon anomaly from first principles to an accuracy of 4.6 per mil

    The anomalous magnetic moment of the muon, as a low energy precision observable, has long served as a test of the Standard Model (SM) of particle physics. The latest muon $g-2$ measurements at Fermilab confirm the previous BNL result, hence emphasizing, up to 5.1 standard deviations, the discrepancy between the experimental world average value and the reference SM prediction. The uncertainty...

    Parallel Session Talk

    Dark-showers offer a compelling collider signature for Hidden Valley models featuring a confining dark sector. Our work extends the investigation of these models to near-conformal theories where the running coupling, controlled by renormalization group equations (RGE), flows near to an infra-red fixed point. We establish a framework of two classes of RGE solutions which cover much of the...

  5. 102. The Standard Model lifetime is slightly shorter
    Dr Yutaro Shoji (IJS)

    Parallel Session Talk

    The electroweak vacuum of the Standard Model is unstable at very high energies due to the running of the Higgs quartic coupling. Since a vacuum decay rate is a fundamental quantity and the Standard Model parameters are precisely measured, its accurate determination is important. We reexamined the computation of vacuum decay rates at the one-loop level and found that the degeneracy factor of...
