The Relationship of the Laplacian Gauge to the Landau Gauge
Jeffrey E. Mandula
The Laplacian gauge for gauge group SU(N) is discussed in perturbation theory. It is shown that to the lowest non-trivial order, O(g^1), configurations in the Laplacian gauge autom…
Gauge Fixing on the Lattice and the Gibbs Phenomenon
Jeffrey E. Mandula
We discuss global gauge fixing on the lattice, specifically to the lattice Landau gauge, with the goal of understanding the question of why the process becomes extremely slow for l…
Heavy Quarks on the Lattice
Jeffrey E. Mandula
This lecture describes the treatment of heavy quarks in lattice QCD by implementing the Isgur-Wise limit. The method is briefly discussed, and some of the special features of the r…
Renormalization of the Classical Velocity in the Lattice Heavy Quark Effective Theory
Jeffrey E. Mandula, Michael C. Ogilvie
In the lattice formulation of the Heavy Quark Effective Theory (LHQET), the classical velocity becomes renormalized. The origin of this renormalization is the reduction of Lorentz…
Numerical Analysis of the Quark Fraction of the Proton Spin
Jeffrey E. Mandula
We report on a lattice QCD estimate of the quark spin fraction of the proton spin. The estimate is arrived at by means of a lattice QCD simulation of the polarized proton matrix el…
