Confining Strings with Topological Term
We consider several aspects of ‘confining strings’, recently proposed to describe the confining phase of gauge field theories. We perform the exact duality transformation that leads to the confining string action and show that it reduces to the Polyakov action in the semiclassical approximation. In 4D we introduce a ‘θ-term’ and compute the low-energy effective action for the confining string i...
متن کاملQED 3 with θ term and axionic confining strings
We discuss three dimensional compact QED with a θ term due to an axionic field. The variational gauge invariant functional is considered and it is shown that the ground state energy is independent of θ in a leading approximation. The mass gap of the axionic field is found to be dependent upon θ, the mass gap of the photon field and the scalar potential. The vacuum expectation of the Wilson loop...
متن کامل0 SU ( 3 ) - inspired confining strings with θ - term
The generalization of 4D confining string theory to the SU(3)-inspired case is derived. It describes string representation of the Wilson loop in the SU(3)-analogue of compact QED extended by the θ-term. It is shown that although the obtained theory of confining strings differs from that of compact QED, their low-energy limits have the same functional form. This fact leads to the appearance of t...

متن کاملSU(N) confining strings
String representations of the SU(N)-version of compact QED in three and four dimensions are constructed. Using for concreteness the three-dimensional case, it is demonstrated how the resulting SU(N)-generalization of the so-called theory of confining strings can be obtained in various ways. Such an SU(N)-theory of confining strings is then compared with the approach to the derivation of the str...
