Abstract :
SAPQCD, the Abelian projection QCD (APQCD) action, is evaluated using the demon method. For SU(2), SAPQCD at strong coupling is essentially the compact QED (CQED) action with βCQED = 12βSU(2): extended and higher representation plaquettes are absent. Since CQED deconfines when βCQED>∼ 1, this relation must break down as βSU(2) → 2. Indeed we find SAPQCD mutates: near βSU(2) ∼ 2 it gains additional operators, including an exogenous negative magnetic monopole mass shift. SAPQCD for SU(3) has similar behavior. The Appendix gives a brief explanation of the demon method.
