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…

Efficient lattice QCD computation of radiative-leptonic-decay form factors at multiple positive and negative photon virtualities
Davide Giusti, Christopher F. Kane, Christoph Lehner +2
In previous work Phys. Rev. D 107, 074507 (2023), we showed that form factors for radiative leptonic decays of pseudoscalar mesons can be determined efficiently and with high preci…
