چکیده

We propose a novel type of color magnetic condensation originating from magnetic monopoles so that it provides the mass of off-diagonal gluons in the Yang-Mills theory. This dynamical mass generation enables us to explain the infrared Abelian dominance and monopole dominance by way of a non-Abelian Stokes theorem, which supports the dual superconductivity picture of quark confinement. Moreover, we show that the instability of Savvidy vacuum disappears by sufficiently large color magnetic condensation.

Magnetic condensation , Abelian dominance , and instability of Savvidy vacuum

We show that a certain type of color magnetic condensation originating from magnetic monopole configurations is sufficient to provide the mass for off-diagonal gluons in the SU(2) Yang-Mills theory under the Cho–Faddeev– Niemi decomposition. In fact, such magnetic condensation is shown to occur by calculating the effective potential within the BRST quantization. This enables us to explain the i...

Numerical evidence for the existence of a novel magnetic condensation in Yang-Mills theory

We present a first numerical evidence for the existence of a novel magnetic condensate proposed recently by one of the authors in SU(2) Yang-Mills theory. In our framework, the spontaneously generated color magnetic field identified with the Savvidy vacuum has the microscopic origin and is a consequence of the intrinsic dynamics of the Yang-Mills theory. It strongly suggests the Nielsen– Olesen...

Gauge-invariant gluon mass, infrared Abelian dominance and stability of magnetic vacuum

We give an argument for deriving analytically the infrared “Abelian” dominance in a gauge invariant way for the Wilson loop average in SU(2) Yang– Mills theory. In other words, we propose a possible mechanism for realizing the dynamical Abelian projection in the SU(2) gauge-invariant manner without breaking color symmetry. This supports validity of the dual superconductivity picture for quark c...

Dual superconductivity , monopole condensation and confining string in low - energy Yang - Mills theory . Part

We show that the QCD vacuum (without dynamical quarks) is a dual supercon-ductor at least in the low-energy region in the sense that monopole condensation does really occur. In fact, we derive the dual Ginzburg-Landau theory (i.e., dual Abelian Higgs model) directly from the SU(2) Yang-Mills theory by adopting the maximal Abelian gauge. The dual superconductor can be on the border between type ...

Non-Abelian variation on the Savvidy vacuum of the Yang-Mills gauge theory.

As a prelude to a truly non-perturbative evaluation of the e ective potential in terms of lattice QCD, the one loop e ective potential for a non-Abelian gauge con guration is calculated using the background eld method. Through a non-trivial correlation between the space and color orientations the new background eld avoids the possible coordinate singularity, DetBa i = 0, observed recently by Ke...
