ABELIAN DOMINANCE OF CHIRAL-SYMMETRY BREAKING IN LATTICE QCD

Calculations of the chiral condensate (RX) on the lattice using stagge red fermions and the Lanczos algorithm are presented. Four gauge field s are considered: the quenched non-Abelian field, an Abelian-projected field, and monopole and photon fields further decomposed from the Abe lian field. Abelian projection is performed in the maximal Abelian gau ge and in the Polyakov gauge. The results show that monopoles in the m aximal Abelian gauge largely reproduce the chiral condensate values of the full non-Abelian theory, in both SU(2) and SU(3) color.
