Abstract
By means of a special choice of gauge QCD 2 [SU( N)] with one flavor of quarks is recast into the Bose form. Weak ( g ⪡ m) and strong ( g⪡ m) coupling regimes are studied. The former is shown to be the SU( N)-symmetric confining phase in which bound states possess stringlike configurations with strings being represented by electric vortex lines; the ordinary mesons and baryons appear as longitudinal modes of electric strings. The strong coupling regime describes the Higgs phase with the residual symmetry [U(1)] N−1 ⊗ S N where the left and right factors are the maximal abelian subgroup of SU( N) and the permutation group of N quarks, respectively; the particle spectrum consists of S N multiplets and the [Uw(1)] N−1 charges are trapped.
