Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\%
A. Boccaletti, Sz. Borsanyi, A. Cotellucci +19
We present a new lattice QCD calculation of the leading order hadronic vacuum polarization (LO-HVP) contribution to the muon anomalous magnetic moment . We reduce uncertaintie…

The three-pion -matrix at NLO in ChPT
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3
The three-particle -matrix, , is a scheme-dependent quantity that parametrizes short-range three-particle interactions in the relativistic-field-the…

Three-pion scattering: From the chiral Lagrangian to the lattice
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3
In recent years, detailed studies of three-pion systems have become possible in lattice QCD. This has in turn led to interest in 3-to-3 scattering of pions in the chiral perturbati…
