Morning session 5: Lattice Simulation for Hadron Phenomenology
- Atsushi Nakamura (FEFU / Osaka Univ.)
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.
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)...
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.
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...
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...
