Hyperasymptotics and quark-hadron duality violations in QCD
Diogo Boito, Irinel Caprini, Maarten Golterman +2
We investigate the origin of the quark-hadron duality-violating terms in the expansion of the QCD two-point vector correlation function at large energies in the complex plane…
More on heavy tetraquarks in lattice QCD at almost physical pion mass
Anthony Francis, Renwick J. Hudspith, Randy Lewis +1
We report on our progress in studying exotic, heavy tetraquark states, . Using publicly available dynamical Wilson-Clover gauge configuratio…
Pion mass dependence of the HVP contribution to muon
Maarten Golterman, Kim Maltman, Santiago Peris
One of the systematic errors in some of the current lattice computations of the HVP contribution to the muon anomalous magnetic moment is that associated with the extrapolati…
Hadronic tau decays and the strong coupling
Diogo Boito, Maarten Golterman, Kim Maltman +1
We provide an overview of recent determinations of the strong coupling, , from hadronic decays. We contrast two analysis methods, the "truncated-OPE approach" and the "DV-…
Determination of the NNLO low-energy constant
Maarten Golterman, Kim Maltman, Santiago Peris
Experimental data from hadronic decays allow for a precision determination of the slope of the vacuum polarization at zero momentum. We use this information to provide a…
A resolution of the inclusive flavor-breaking puzzle
Renwick J. Hudspith, Randy Lewis, Kim Maltman +1
We revisit the puzzle of values obtained from the conventional implementation of hadronic--decay-based flavor-breaking finite-energy sum rules lying below the…
