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…
Prospects of calculating and from lattice QCD
Rajan Gupta
An overview of lattice results for the strange quark mass, , , , and is presented. I give my assessment of the reliability of various estimates and prospects f…
General Physics Motivations for Numerical Simulations of Quantum Field Theory
Rajan Gupta
In this introductory article a brief description of Quantum Field Theories (QFT) is presented with emphasis on the distinction between strongly and weakly coupled theories. A case…
