Including electromagnetism in decay calculations
Norman Christ, Xu Feng
Because of the small size of the ratio A_2/A_0 of the I=2 to I=0 K -> pipi decay amplitudes (the Delta I=1/2 rule) the effects of electromagnetism on A_2 may be a factor of 20 larg…
Lattice QCD Application Development within the US DOE Exascale Computing Project
Richard Brower, Norman Christ, Carleton DeTar +2
In October, 2016, the US Department of Energy launched the Exascale Computing Project, which aims to deploy exascale computing resources for science and engineering in the early 20…
Testing algorithms for critical slowing down
Guido Cossu, Peter Boyle, Norman Christ +3
We present the preliminary tests on two modifications of the Hybrid Monte Carlo (HMC) algorithm. Both algorithms are designed to travel much farther in the Hamiltonian phase space…
Using infinite volume, continuum QED and lattice QCD for the hadronic light-by-light contribution to the muon anomalous magnetic moment
Thomas Blum, Norman Christ, Masashi Hayakawa +4
In our previous work, the connected and leading disconnected hadronic light-by-light contributions to the muon anomalous magnetic moment (g - 2) have been computed using lattice QC…
Exploratory Lattice QCD Study of the Rare Kaon Decay
Ziyuan Bai, Norman H. Christ, Xu Feng +3
We report a first, complete lattice QCD calculation of the long-distance contribution to the decay within the standard model. This is a second-order weak process…
