Quantizing the line element field

A metric with signature (-+++) can be constructed from a metric with signature (++++) and a double-sided vector field called the line element field. Some of the classical and quantum properties of this vector field are studied.Comment: 9 page

Aspects of Dynamical Chiral Symmetry Breaking

Dynamical chiral symmetry breaking is a nonperturbative phenomenon that may be studied using QCD's gap equation. Model-independent results can be obtained with a nonperturbative and symmetry preserving truncation. The gap equation yields the massive dressed-quark propagator, which has a spectral representation when considered as a function of the current-quark mass. This enables an explication of the connection between the infrared limit of the QCD Dirac operator's spectrum and the quark condensate appearing in the operator product expansion.Comment: 11, LaTeX2e, ws-procs9x6; contribution to proceedings of the "5th International Conference on Quark Confinement and the Hadron Spectrum," Gargnano, Italy, 10-14/Sept./0
