The effect is similar to instanton induced chiral symmetry breaking in 3+1 dimensions and is due to the interaction of quark propagators with sphalerons. The existence of sphalerons requires that color symmetries be broken by a Higgs in the fundamental representation. We show that the sphaleron effect may persist for arbitrarily large $N_f$ but vanishes along with the mass of the gauge fields corresponding to broken generators of $SU(N_c)$. The effect is inherently non-Abelian and absent for QED.", "revisions": [ { "version": "v1", "updated": "1998-06-22T22:00:49.000Z" } ], "analyses": { "keywords": [ "dimensions", "fundamental representation", "dimensional gauge thories", "broken generators", "quark condensation" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
