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 e…
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 l…
Exploiting stochastic locality in lattice QCD: hadronic observables and their uncertainties
Mattia Bruno, Marco Cè, Anthony Francis +4
Because of the mass gap, lattice QCD simulations exhibit stochastic locality: distant regions of the lattice fluctuate independently. There is a long history of exploiting this to…
Isospin 0 and 2 two-pion scattering at physical pion mass using distillation with periodic boundary conditions in lattice QCD
Mattia Bruno, Daniel Hoying, Taku Izubuchi +3
The two pion channel in Lattice QCD has long been a primary testing ground for studying multiparticle scattering in finite volume QCD. With the development of sophisticated techniq…
Isospin 0 and 2 two-pion scattering at physical pion mass using all-to-all propagators with periodic boundary conditions in lattice QCD
Thomas Blum, Peter A. Boyle, Mattia Bruno +9
A study of two-pion scattering for the isospin channels, and , using lattice QCD is presented. Möbius domain wall fermions on top of the Iwasaki-DSDR gauge action for gl…
Variations on the Maiani-Testa approach and the inverse problem
Mattia Bruno, Maxwell T. Hansen
We discuss a method to construct hadronic scattering and decay amplitudes from Euclidean correlators, by combining the approach of a regulated inverse Laplace transform with the wo…
Direct CP violation and the rule in decay from the Standard Model
Ryan Abbott, Thomas Blum, Peter A. Boyle +12
We present a lattice QCD calculation of the , decay amplitude and , the measure of direct CP-violation in decay, improving our 2015 ca…
Light quark masses in N_f = 2+1 lattice QCD with Wilson fermions
Mattia Bruno, Isabel Campos, Patrick Fritzsch +5
We present a lattice QCD determination of light quark masses with three sea-quark flavours (). Bare quark masses are known from PCAC relations in the framework of CLS la…
Light and strange quark masses from simulations with Wilson fermions
M. Bruno, I. Campos, J. Koponen +4
We present a nearly final analysis of the and quark masses, extracted using the PCAC quark masses reported in [PRD 95 (2017) 074504]. The data is based on the CLS $N_f =…
The -parameter in 3-flavour QCD and by the ALPHA collaboration
M. Bruno, M. Dalla Brida, P. Fritzsch +6
We present results by the ALPHA collaboration for the -parameter in 3-flavour QCD and the strong coupling constant at the electroweak scale, , in terms of hadronic qua…
