Leading hadronic contribution to the muon magnetic moment from lattice QCD
Sz. Borsanyi,Z. Fodor,Jana N. Guenther,Christian Hoelbling,S. D. Katz,Laurent Lellouch,Th. Lippert,Th. Lippert,Kohtaroh Miura,Kohtaroh Miura,L. Parato,Kalman K. Szabo,Kalman K. Szabo,Finn M. Stokes,Bálint C. Tóth,Cs. Torok,L. Varnhorst,L. Varnhorst +17 more
TL;DR: Substantial precision is reached to discriminate between the measurement of the anomalous magnetic moment of the muon and the predictions of dispersive methods, which favours the experimentally measured value over those obtained using the dispersion relation.

TL;DR: In this article, the anomalous magnetic moment of the muon was determined based on ab initio quantum chromodynamics and quantum electrodynamics simulations, and the experimental results were used to discriminate between the measurement of the magnetic moment and the predictions of dispersive methods.

Ab-initio calculation of the proton and the neutron's scalar couplings for new physics searches
Sz. Borsanyi,Z. Fodor,C. Hoelbling,L. Lellouch,Kalman K. Szabo,Christian Torrero,L. Varnhorst +6 more
TL;DR: In this paper, a fully-controlled, ab-initio calculation of these couplings to the quarks within those constituents of nuclei is presented, using lattice quantum chromodynamics computations for the four lightest species of quarks and heavy quark expansions for the remaining two.
Proceedings ArticleDOI
Topology changing update algorithms for SU(3) gauge theory
TL;DR: In this article , the authors study the problem and possible algorithmic solutions in 4-dimensional SU(3) gauge theory, with special focus on instanton updates and Metadynamics.
