Lattice determination of the $K \to (π π)_{I = 2}$ Decay Amplitude $A_{2}$

T. Blum, P. A. Boyle, N. H. Christ +13

We describe the computation of the amplitude A_2 for a kaon to decay into two pions with isospin I=2. The results presented in the letter Phys.Rev.Lett. 108 (2012) 141601 from an a…

Light Quark Mass Reweighting

Qi Liu, Norman H. Christ, Chulwoo Jung

We present a systematic study of the effectiveness of light quark mass reweighting. This method allows a single lattice QCD ensemble, generated with a specific value of the dynamic…

Practical methods for a direct calculation of $Δ I = 1/2$ $K$ to $π π$ Decay

Qi Liu

A direct calculation of the complex $Δ I = 1/2$ kaon decay amplitude is notoriously difficult because of the presence of disconnected graphs. Here we describe and demonstrate two prac…

The $K \to (π π)_{I = 2}$ Decay Amplitude from Lattice QCD

T. Blum, P. A. Boyle, N. H. Christ +13

We report on the first realistic \emph{ab initio} calculation of a hadronic weak decay, that of the amplitude $A_{2}$ for a kaon to decay into two π-mesons with isospin 2. We find Re…

$K$ to $π π$ Decay amplitudes from Lattice QCD

T. Blum, P. A. Boyle, N. H. Christ +11

We report a direct lattice calculation of the $K$ to $π π$ decay matrix elements for both the $Δ I = 1/2$ and 3/2 amplitudes $A_{0}$ and $A_{2}$ on 2+1 flavor, domain wall fermion, $16^3\t…

Preliminary results of $Δ I = 1/2$ and $3/2$ , $K$ to $π π$ Decay Amplitudes from Lattice QCD

Qi Liu, RBC, UKQCD collaborations

We report a direct lattice calculation of the $K$ to $π π$ decay matrix elements for both $Δ I = 1/2$ and $3/2$ channels on 2+1 flavor, domain wall fermion, $1 6^{3} \times 32$ lattices wit…

The $η$ and $η^{'}$ mesons from Lattice QCD

N. H. Christ, C. Dawson, T. Izubuchi +6

The large mass of the ninth pseudoscalar meson, the $η^{'}$ , is believed to arise from the combined effects of the axial anomaly and the gauge field topology present in QCD. We…

Two pion scattering, I=0 and disconnected diagrams in Lattice QCD

Qi Liu

A full, high-statistic I=0 and I=2 $π - π$ scattering calculation including the disconnected diagram is performed on 2+1 flavor, domain wall fermion gauge configurations generated us…
