Isospin-breaking effects in inclusive hadronic data for the muon from first principles
Mattia Bruno, Taku Izubuchi, Christoph Lehner +3
The knowledge of isospin-breaking effects in hadronic decays is required for a high-precision determination of the Hadronic-Vacuum-Polarization contribution to from…
Towards the time-like pion form factor beyond the elastic regime using domain-wall QCD
Gabriele Morandi, Mattia Bruno, Francesca Argia Bresciani +2
In this work, we investigate the time-like pion form factor from lattice QCD in the isosymmetric limit, a quantity that plays an important role in understanding hadron physics with…
Isospin breaking corrections to the hadronic vacuum polarization with stochastic coordinate sampling
Mattia Bruno, Vera Gülpers, Nils Hermansson-Truedsson +3
In the recent Muon g-2 Theory Initiative white paper update, the hadronic vacuum polarization (HVP) contribution -- which dominates the theoretical uncertainty -- is evaluated as a…
Lattice QCD calculation of the -pole contribution to the hadronic light-by-light scattering in the anomalous magnetic moment of the muon
Tian Lin, Mattia Bruno, Xu Feng +4
We develop a method to compute the pion transition form factor directly at arbitrary space-like photon momenta and use it to determine the -pole contribution to the hadronic…
