Continuum extrapolation of with staggered fermions
Weonjong Lee, Yong-Chull Jang, Hyung-Jin Kim +8
We report on recent progress in the calculation of using HYP-smeared staggered fermions on the MILC asqtad lattices. Our main focus is on the continuum extrapolation, which i…
Kaon -parameter from improved staggered fermions in QCD
Taegil Bae, Yong-Chull Jang, Chulwoo Jung +9
We present a calculation of the kaon -parameter, , using lattice QCD. We use improved staggered valence and sea fermions, the latter generated by the MILC collaboration wit…
Trouble shooting for covariance fitting in highly correlated data
Boram Yoon, Yong-Chull Jang, Weonjong Lee +1
We report a possible solution to the trouble that the covariance fitting fails when the data is highly correlated and the covariance matrix has small eigenvalues. As an example, we…
from improved staggered fermions using SU(3) chiral perturbation theory
Kwangwoo Kim, Yong-Chull Jang, Hyung-Jin Kim +8
We present recent progress in our calculation of with improved staggered fermions using chiral extrapolations based on SU(3) staggered chiral perturbation theory. We have acc…
Covariance fitting of highly correlated data in lattice QCD
Boram Yoon, Yong-Chull Jang, Chulwoo Jung +1
We address a frequently asked question on the covariance fitting of the highly correlated data such as our data based on the SU(2) staggered chiral perturbation theory. Basic…
