DOI: 10.1103/physrevd.107.074506
Abstract: We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, $a_{\mu}^{\rm HVP}$, in the so-called short and intermediate time-distance windows, $a_{\mu}^{\rm SD}$ and $a_{\mu}^{\rm W}$, defined… read more here.

DOI: 10.1103/physrevd.111.034006
Abstract: We discuss the central and, mostly, spin-dependent potentials in heavy quarkonia b¯b,c¯c, with two goals in mind. The first is phenomenological: using the splitting between the 1S and 2S pairs, as well as the 1P… read more here.

DOI: 10.1103/physrevlett.134.011902
Abstract: The hadronic vacuum polarization (HVP) contributions to the muon g-2 are the crucial quantity to resolve whether new physics is present or not in the comparison between the standard model (SM) prediction and experimental measurements… read more here.
