  1. 32. Heavy quark spectral functions and charm diffusion
    Dr Olaf Kaczmarek (Bielefeld University)

    Lattice Simulations for Hadron Phenomenology

    I will discuss recent results of quarkonium spectral functions and heavy quark diffusion coefficients. Our results are based on continuum extrapolated lattice correlation functions and spectral reconstructions that are constrained by perturbation theory.

  2. 38. QCD phase transition for various number of flavours

    Lattice Simulations for Hadron Phenomenology

    We discuss thermal QCD phase transition for various number of flavours. We review the results for the transition from $N_f=3$ to larger values. We discuss the universality class for $N_f=2$, along the critical line for two massless light flavours and a third flavour whose mass serves as an interpolator between $N_f=2$ and $N_f=3$. We identify a possible scaling window for the 3D O(4)...

  3. 24. The $\eta$/$\eta'$ system and large-$N_c$ ChPT: A Lattice QCD Study
    Gunnar Bali (Universität Regensburg)

    Lattice Simulations for Hadron Phenomenology

    We compute the masses, decay constants and gluonic matrix elements on the $\eta$ and $\eta'$ mesons in lattice simulations across four lattice spacings with the light quark masses reaching down to the physical point. A comparison is made to the Large-$N_c$ chiral perturbation theory (ChPT) predictions and the NLO low energy constants are determined.

  4. 35. Static quark-antiquark interactions at non-zero temperature from lattice QCD
    Johannes Heinrich Weber (Humboldt-Universität zu Berlin)

    Lattice Simulations for Hadron Phenomenology

    We study the interactions of a static quark-antiquark pair at non-zero temperature using realistic (2+1)-flavor lattice QCD calculations. The study consists of two parts: the first investigates the properties of Wilson line correlators in Coulomb gauge and compares to predictions of hard-thermal loop perturbation theory. As a second step we extract the spectral functions underlying the...

  5. 17. A lattice QCD view of the hadronic contributions to the anomalous magnetic moment of the muon
    Проф. Harvey Meyer (Johannes Gutenberg University Mainz)

    Lattice Simulations for Hadron Phenomenology

    The recent confirmation of the Brookhaven measurement of the anomalous
    magnetic of the muon by the Fermilab g-2 experiment has increased the
    tension with the theory prediction for g-2 compiled in a 2020 White Paper.
    The uncertainty of the theory prediction is entirely dominated by the
    hadronic vacuum polarisation (HVP) and the hadronic light-by-light (HLbL)
    contributions. I review the status...
