Ansatz Approach

With the aim of developing covariant QCD-based models of hadrons we study dynamical chiral symmetry breaking in an ansatz approach to QCD. The quark self-energy is calculated from the Schwinger-Dyson equation using an ansatz for the proper quark-gluon vertex consistent with QCD symmetries. Both asymptotic freedom and behavior consistent with confinement are included in the dressed gluon propagator. With essentially one free parameter we find that we can obtain good results for physically relevant quantities including the pion decay constant fπ, the quark condensate [Formula: see text], the scale parameter ΛQCD, and the constituent quark mass.

The center vortex model of quantum-chromodynamics can explain confinement and chiral symmetry breaking. We present a possible resolution for problems of the vortex detection in smooth configurations and discuss improvements for the detection of center vortices.
