Formal Naive Dirac Operators and Graph Topology
G. M. von Hippel
Motivated by a recent conjecture of Misumi and Yumoto relating the number of zero modes of lattice Dirac operators to the sum of the Betti numbers of the underlying spacetime manif…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…
Zemach and Friar radii of the proton and neutron from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
We present the first lattice-QCD result for the Zemach and Friar radii of the proton and neutron. Our calculation includes both quark-connected and -disconnected diagrams and asses…
Precision calculation of the electromagnetic radii of the proton and neutron from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
We present lattice-QCD results for the electromagnetic form factors of the proton and neutron including both quark-connected and -disconnected contributions. The parametrization of…
Electromagnetic form factors of the nucleon from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
There is a long-standing discrepancy between different measurements of the electric and magnetic radii of the proton. Lattice QCD calculations are a well-suited tool for theoretica…
