چکیده

The pattern of spontaneous chiral symmetry breaking (CSB) in confining background fields is analyzed. It is explicitly demonstrated how the needed for CSB inverse square root large proper time asymptotic of the operator product expansion can be obtained.

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 ...

Restoration of chiral and U(1)A symmetries in excited hadrons.

1 Restoration of chiral and U (1) A symmetries in excited hadrons. The effective restoration of SU(2) L × SU(2) R and U(1) A chiral symmetries of QCD in excited hadrons is reviewed. While the low-lying hadron spectrum is mostly shaped by the spontaneous breaking of chiral symmetry, in the high-lying hadrons the role of the quark con-densate of the vacuum becomes negligible and the chiral symmet...

OPE–RχT matching at order αs: hard gluonic corrections to three–point Green functions

In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RχT) to order αs. To this end we compute two– and three–point QCD Green functions (GFs) in both theories and compare the results. GFs which are order parameters of chiral symmetry breaking make this matching more transparent and thus we concentrate on those. On the OPE side one needs ...

The Dual Meissner Effect description of QCD in the confining region provides 1 q 4 behaviour for the gluon propagator and involves the dual gluon mass m as a parameter. This is used in the Schwinger-Dyson equation for the quarks in the infrared region to exhibit chiral symmetry breaking for light quarks. Using the light quark condensate as input, the dual gluon mass is determined and its import...
