The parameter in the overlap on domain-wall mixed action
M. Lujan, A. Alexandru, T. Draper +6
A direct calculation of the mixed-action parameter with valence overlap fermions on a domain-wall fermion sea is presented. The calculation is performed on four ensembles…
Chiral extrapolation beyond the power-counting regime
J. M. M. Hall, F. X. Lee, D. B. Leinweber +4
Chiral effective field theory can provide valuable insight into the chiral physics of hadrons when used in conjunction with non-perturbative schemes such as lattice QCD. In this di…
Overlap Valence on 2+1 Flavor Domain Wall Fermion Configurations with Deflation and Low-mode Substitution
A. Li, A. Alexandru, Y. Chen +11
The overlap fermion propagator is calculated on 2+1 flavor domain wall fermion gauge configurations on 16^3 x 32, 24^3 x 64 and 32^3 x 64 lattices. With HYP smearing and low eigenm…
Magnetic moments of vector, axial, and tensor mesons in lattice QCD
F. X. Lee, S. Moerschbacher, W. Wilcox
We present a calculation of magnetic moments for selected spin-1 mesons using the techniques of lattice QCD. This is carried out by introducing progressively small static magnetic…
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…
