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…
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…
Effects of dynamical sea-quarks on quark and gluon propagators
Maria B. Parappilly, Patrick O. Bowman, Urs M. Heller +3
We present an unquenched calculation of the quark propagator in Landau gauge with 2+1 flavors of dynamical quarks. We study the scaling behavior of the quark propagator in full QCD…
Scaling behavior of quark propagator in full QCD
Maria B. Parappilly, Patrick O. Bowman, Urs M. Heller +3
We study the scaling behavior of the quark propagator on two lattices with similar physical volume in Landau gauge with 2+1 flavors of dynamical quarks in order to test whether we…
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…
