Nonperturbative QCD Vacuum Effects in Nonlocal Quark Dynamics
K. Williams
A straightforward calculation reveals the essentially nonlocal character of the leading heavy interaction arising from nonperturbative gluon field correlations in the mo…
Flux Tubes in Effective Field Theory
M. G. Olsson, S. Veseli, K. Williams
Quark-antiquark bound states are examined in the long-range strong-coupling limit with the minimal area law of lattice gauge theory assumed as input. Matrix element relations are e…
On the validity of the reduced Salpeter equation
M. G. Olsson, S. Veseli, K. Williams
We adapt a general method to solve both the full and reduced Salpeter equations and systematically explore the conditions under which these two equations give equivalent results in…
On the instantaneous Bethe-Salpeter equation
M. G. Olsson, S. Veseli, K. Williams
We present a systematic algebraic and numerical investigation of the instantaneous Bethe-Salpeter equation. Emphasis is placed on confining interaction kernels of the Lorentz scala…
Fermion Confinement by a Relativistic Flux Tube
M. G. Olsson, S. Veseli, K. Williams
We formulate the description of the dynamic confinement of a single fermion by a flux tube. The range of applicability of this model extends from the relativistic corrections of a…
Observations On the Potential Confinement of a Light Fermion
M. G. Olsson, S. Veseli, K. Williams
We consider possible dynamical models for a light fermion confined by a potential field. With the Dirac equation only Lorentz scalar confinement yields normalizable wavefunctions,…
