The effective dipole-type field approach and the dual Higgs model

The flux-tube phase transition and bound states at high temperatures

“…We found that the phase transition temperature essentially depends on α(Q) and the mass of the dual gaugeˇeld m. The analytic criterion constraining the existence of a quarkÄantiquark bound state at T > T c is obtained (see (12) and (15)). Weˇnd that the Coulomb string tension for strongly interacting particles in deconˇnement increases with α 2 T 2 , and at short distances the Coulomb potential has the linear rising.…”

“…All the particles become massive. The v.e.v.B 0i produce a color monopole generating current conˇning the electric color ux [12]:…”

“…The temperature-dependent ux-tube solution for the dual gaugeˇled along the z-axis (within the cylindrical symmetry) has the following asymptotic transverse behaviour (for details see [12] at T = 0):…”

“…We study the model of Lagrangian where the fundamental variables are an octet of dual potentials coupled minimally to three octets of monopole (Higgs-like)ˇelds [12].…”

“…The scope of commutation relations, two-point Wightman functions and Green's functions as well-deˇned distributions in the space S( d ) of complex Schwarz test functions on d , the monopole-and dual gauge-ˇeld propagations, the asymptotic transverse behaviour of both the dual gaugeˇeld and the color-electricˇeld, the analytic expression for the static potential can be found in [12].…”
