Lattice QCD determination of patterns of excited baryon states (2007)
Basak, Subhasish, Edwards, R. G., Fleming, G. T., Juge, K. J., Lichtl, A., Morningstar, C., ...
Energies for excited isospin I=1/2 and I=3/2 states that include the nucleon and Delta families of baryons are computed using quenched, anisotropic lattices. Baryon interpolating field operators that...
Combining Quark and Link Smearing to Improve Extended Baryon Operators (2005)
Lichtl, Adam, Basak, Subhasish, Edwards, Robert, Fleming, George T., Heller, Urs M., Morningstar, Colin, ...
The effects of Gaussian quark-field smearing and analytic stout-link smearing on the correlations of gauge-invariant extended baryon operators are studied. Gaussian quark-field smearing substantially...
Clebsch-Gordan Construction of Lattice Interpolating Fields for Excited Baryons (2005)
Basak, Subhasish, Edwards, Robert, Fleming, George T., Heller, Urs M., Morningstar, Colin, Richards, David, ...
Large sets of baryon interpolating field operators are developed for use in lattice QCD studies of baryons with zero momentum. Operators are classified according to the double-valued irreducible...
On the continuum limit of gauge-fixed compact U(1) lattice gauge theory (2003)
Basak, Subhasish, De, Asit K, Sinha, Tilak
We investigate the continuum limit of a compact formulation of the lattice U(1) gauge theory in 4 dimensions using a nonperturbative gauge-fixed regularization. We find clear evidence of a continuous...
