On the Locality and Scaling of Overlap Fermions at Coarse Lattice Spacings
Terrence Draper, Nilmani Mathur, Jianbo Zhang +7
The overlap fermion offers the considerable advantage of exact chiral symmetry on the lattice, but is numerically intensive. This can be made affordable while still providing large…
Scalar Mesons a0(1450) and sigma(600) from Lattice QCD
Nilmani Mathur, A. Alexandru, Y. Chen +7
We study the a0 and sigma mesons with the overlap fermion in the chiral regime with the pion mass as low as 182 MeV in the quenched approximation. After the eta'pi ghost states are…
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…
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…
