Domain wall QCD with physical quark masses

RBC, UKQCD collaborations, : +21

We present results for several light hadronic quantities ( $f_{I ¨} $ , $f_{K}$ , $B_{K}$ , $m_{u d}$ , $m_{s}$ , $t_{0}^{1/2}$ , $w_{0}$ ) obtained from simulations of 2+1 flavor domain wall lattice QCD…

$K \to I ¨ I ¨ $ $I^ I = 3/2$ decay amplitude in the continuum limit

T. Blum, P. A. Boyle, N. H. Christ +12

We present new results for the amplitude $A_{2}$ for a kaon to decay into two pions with isospin $I = 2$ : Re $A_{2} = 1.50 (4)_{stat} (14)_{syst} \times 1 0^{- 8}$ GeV; Im$A_2 =…

Emerging understanding of the ÎI = 1/2 Rule from Lattice QCD

P. A. Boyle, N. H. Christ, N. Garron +8

There has been much speculation as to the origin of the ÎI = 1/2 rule (Re A_0/Re A_2 \simeq 22.5). We find that the two dominant contributions to the ÎI=3/2, K \to ÏÏ correlati…

Electromagnetic finite-size effects to the hadronic vacuum polarization

J. Bijnens, J. Harrison, N. Hermansson-Truedsson +3

In order to reduce the current hadronic uncertainties in the theory prediction for the anomalous magnetic moment of the muon, lattice calculations need to reach sub-percent accurac…

Determination of the $A_{2}$ amplitude of $K \to I ¨ I ¨ $ decays

T. Janowski, C. T. Sachrajda, P. A. Boyle +6

We review the status of recent calculations by the RBC-UKQCD collaboration of the complex amplitude $A_{2}$ , corresponding to the decay of a kaon to a two pion state with total isosp…
