Chiral Symmetry Breaking and Dual Gluon Mass in the Confining Region of QCD
Abstract
The Dual Meissner Effect description of QCD in the confining region provides 1q4 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 importance in showing the asymptotic free behaviour of the extrinsic curvature coupling in the rigid QCD string is discussed.
