String tension and glueball masses of SU(2) QCD from perfect action for monopoles and strings

Abstract: We study the perfect monopole action as an infrared effective theory of SU(2) QCD. It is transformed exactly into a lattice string model. Since the monopole interactions are weak in the infrared SU(2) QCD, the string interactions become strong. The strong coupling expansion of string model shows the quantum fluctuation is small. The classical string tension and the glueball mass are estimated analytically, and we see it is very close to the quantum one in the SU(2) QCD.
