The connected and leading disconnected diagrams of the hadronic light-by-light contribution to muon
Luchang Jin, Thomas Blum, Norman Christ +4
We report our recent lattice calculation of hadronic light-by-light contribution to muon using our recently developed moment method. The connected diagrams and the leading di…
On calculating disconnected-type hadronic light-by-light scattering diagrams from lattice QCD
Masashi Hayakawa, Thomas Blum, Norman Christ +3
For reliable comparison of the standard model prediction to the muon g-2 with its experimental value, the hadronic light-by-light scattering (HLbL) contribution must be calculated…
Hadronic Light by Light Contributions to the Muon Anomalous Magnetic Moment With Physical Pions
Luchang Jin, Thomas Blum, Norman Christ +3
The current measurement of muonic disagrees with the theoretical calculation by about 3 standard deviations. Hadronic vacuum polarization (HVP) and hadronic light by light…
Covariant approximation averaging
Eigo Shintani, Rudy Arthur, Thomas Blum +3
We present a new class of statistical error reduction techniques for Monte-Carlo simulations. Using covariant symmetries, we show that correlation functions can be constructed from…
Non-degenerate light quark masses from 2+1f lattice QCD+QED
Shane Drury, Thomas Blum, Masashi Hayakawa +3
We report on a calculation of the effects of isospin breaking in Lattice QCD+QED. This involves using Chiral Perturbation Theory with Electromagnetic corrections to find the renorm…
The muon anomalous magnetic moment, a view from the lattice
Christopher Aubin, Thomas Blum, Maarten Golterman +2
We review some of the issues that arise in attempts to compute the hadronic corrections to the muon anomalous magnetic moment using Lattice QCD. We concentrate on the dominant cont…
Hadronic corrections to the muon anomalous magnetic moment from lattice QCD
T. Blum, M. Hayakawa, T. Izubuchi
After a brief self-contained introduction to the muon anomalous magnetic moment, (g-2), we review the status of lattice calculations of the hadronic vacuum polarization contributio…
Model-independent parametrization of the hadronic vacuum polarization and g-2 for the muon on the lattice
Christopher Aubin, Thomas Blum, Maarten Golterman +1
The leading hadronic contribution to the muon anomalous magnetic moment is given by a weighted integral over euclidean momentum of the hadronic vacuum polarization. This integral i…
Electromagnetic mass splittings of the low lying hadrons and quark masses from 2+1 flavor lattice QCD+QED
T. Blum, T. Doi, M. Hayakawa +4
Results are presented for the electromagnetic mass splittings of the low lying hadrons. These are used to determine the non-degenerate light quark masses. It is found that m_u=2.24…
Isospin symmetry breaking effects in the pion and nucleon masses
Ran Zhou, Thomas Blum, Takumi Doi +3
We investigate the electromagnetic mass splittings in the pseudoscalar meson and nucleon systems by combining 2+1 flavor domain wall fermion gauge configurations, generated by the…
