Estimates of Light Quark Masses from Lattice QCD and QCD Sum rules
Rajan Gupta
This talk reviews the progress made in the determination of the light quark masses using lattice QCD and QCD sum rules. Based on preliminary calculations with three flavors of dyna…
Improved bilinears in unquenched lattice QCD
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +2
We summarize the extent to which one can use Ward identities to non-perturbatively improve flavor singlet and non-singlet bilinears with three flavors of non-degenerate dynamical W…
Status of B_K from Lattice QCD
Rajan Gupta
A brief review of lattice calculations of the bag parameter B_K relevant for understanding indirect CP violation in the neutral kaon sector is given. A status report on current sta…
Order a improved renormalization constants
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +1
We present non-perturbative results for the constants needed for on-shell improvement of bilinear operators composed of Wilson fermions. We work at and 6.2 in the qu…
Fixed-point pure gauge action using RGT
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee
We present a status report on the construction of the classical perfect action using the renormalization group transformation (RGT). We investigate finite volume cor…
Order a improved renormalization constants
T. Bhattacharya, R. Gupta, W. Lee +1
We impose the axial and vector Ward identities on local fermion bilinear operators in the Sheikholesalami-Wohlert discretization of fermions. From this we obtain all the coefficien…
