An exploratory calculation of decay from Lattice QCD at physical pion mass
Peter Boyle, En-Hung Chao, Norman Christ +3
We compute the complex, long-distance two-photon-exchange amplitude which contributes to the rare decay from lattice QCD. We use a phys…
Lattice QCD calculation of decay
Norman Christ, Xu Feng, Luchang Jin +2
We extend the application of lattice QCD to the two-photon-mediated, order rare decay . By combining Minkowski- and Euclidean-space methods we are abl…
Gauge-Fixed Fourier Acceleration
Ahmed Sheta, Yidi Zhao, Norman H. Christ
For an asymptotically free theory, a promising strategy for eliminating Critical Slowing Down (CSD) is naïve Fourier acceleration. This requires the introduction of gauge-fixing in…
Calculating the Two-photon Contribution to Decay Amplitude
Norman H. Christ, Xu Feng, Luchang Jin +2
We develop a new method that allows us to deal with two-photon intermediate states in a lattice QCD calculation. We apply this method to perform a first-principles calculation of t…
Numerical Implementation of Gauge-Fixed Fourier Acceleration
Yidi Zhao
In hybrid Monte Carlo evolution, by imposing a physical gauge condition, simple Fourier acceleration can be used to generate conjugate momenta and potentially reduce critical slowi…
