Locality and Scaling of Quenched Overlap Fermions
Terrence Draper, Nilmani Mathur, Jianbo Zhang +6
The overlap fermion offers the tremendous advantage of exact chiral symmetry on the lattice, but is numerically intensive. This can be made affordable while still providing large l…
Glueball Spectrum and Matrix Elements on Anisotropic Lattices
Y. Chen, A. Alexandru, S. J. Dong +10
The glueball-to-vacuum matrix elements of local gluonic operators in scalar, tensor, and pseudoscalar channels are investigated numerically on several anisotropic lattices with the…
Charmonium Spectrum from Quenched QCD with Overlap Fermions
S. Tamhankar, A. Alexandru, Y. Chen +7
We present the first study of the charmonium spectrum using overlap fermions, on quenched configurations. Simulations are performed on lattices, with Wilson gauge…
Nonperturbative renormalization of composite operators with overlap fermions
J. B. Zhang, N. Mathur, S. J. Dong +6
We compute non-perturbatively the renormalization constants of composite operators on a quenched lattice with lattice spacing = 0.20 fm for the overlap fermio…
The Negativity of the Overlap-Based Topological Charge Density Correlator in Pure-Glue QCD and the Non-Integrable Nature of its Contact Part
I. Horvath, A. Alexandru, J. B. Zhang +7
We calculate the lattice two-point function of topological charge density in pure-glue QCD using the discretization of the operator based on the overlap Dirac matrix. Utilizing dat…
Inherently Global Nature of Topological Charge Fluctuations in QCD
I. Horvath, A. Alexandru, J. B. Zhang +8
We have recently presented evidence that in configurations dominating the regularized pure-glue QCD path integral, the topological charge density constructed from overlap Dirac ope…
