Two-loop RI/SMOM- matching factors for the renormalization of bi-local operators contributing to
Erik Lundstrum
The measure of indirect CP violation in the neutral kaon system, , is an important precision test of the Standard Model. A first-principles Standard Model prediction of …
Isospin breaking corrections to a lattice QCD calculation of
Norman H. Christ, Erik Lundstrum
Because of the rule, the effects of electromagnetism and the isospin-breaking light quark mass difference on the direct CP violation parameter may be as l…
Extended framework for the hybrid Monte Carlo in lattice gauge theory
Norman H. Christ, Lu-Chang Jin, Christoph Lehner +2
We develop an extended framework for the hybrid Monte Carlo (HMC) algorithm in lattice gauge theory by embedding the group into the space of general complex matrices,$M_N(\…
Generalized HMC using Nambu mechanics for lattice QCD
Erik Lundstrum
I describe a generalization of the hybrid Monte Carlo (HMC) algorithm in which the molecular dynamics (MD) steps utilize Nambu generalized Hamiltonian dynamics. Characterized by mu…
