Uncovering Low-Dimensional Topological Structure in the QCD Vacuum
I. Horvath, S. J. Dong, T. Draper +5
Recently, we have pointed out that sign-coherent 4-dimensional structures can not dominate topological charge fluctuations in QCD vacuum at all scales. Here we show that an enhance…
Study of stochastic estimates of quark loops with unbiased subtraction
Nilmani Mathur, Shao-Jing Dong
Stochastic noise estimator method is a powerful tool to calculate the disconnected insertion involving quark loops. We study the variance reduction technique with unbiased subtract…
Empirical Baye's Method and Test in Very Light Quark Range from The Overlap Lattice QCD
S. J. Dong, T. Draper, I. Horvath +2
Based on Bayesian theorem an empirical Baye's method is discussed. A programming chart for mass spectrum fitting is suggested. A weakly constrained way for getting priors to solve…
Excited baryons from Bayesian priors and overlap fermions
F. X. Lee, S. J. Dong, T. Draper +4
Using the constrained-fitting method based on Bayesian priors, we extract the masses of the two lowest states of octet and decuplet baryons with both parities. The calculation is d…
Quenched Chiral Log and Light Quark Mass from Overlap Fermions
Terrence Draper, Shao-Jing Dong, Ivan Horvath +4
We study the quenched chiral behavior of the pion with mass as low as MeV. The calculation is done on a quenched lattice of size and fm with…
Charmed and Bottom Baryons from Lattice NRQCD
Nilmani Mathur, Randy Lewis, R. M. Woloshyn
The mass spectrum of charmed and bottom baryons has been computed on anisotropic lattices using quenched lattice nonrelativistic QCD. Masses are extracted by using mass splittings…
