SU(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...
متن کاملBaryons and Confining Strings
The potential of three heavy quarks has recently been the object of detailed numerical studies [1,2], which lend support to the so-called Y law, inspired by a string picture of heavy baryons. Here, we study the leading effect of string fluctuations on the potential, the analogue of the Lüscher term [3,4,5] in the quark-antiquark potential. Understanding such corrections to the Y law is particul...
متن کاملGeometric Aspects of Confining Strings
Confining strings in 4D are effective, thick strings describing the confinement phase of compact U(1) and, possibly, also non-Abelian gauge fields. We show that these strings are dual to the gauge fields, inasmuch their perturbative regime corresponds to the strong coupling (e ≫ 1) regime of the gauge theory. In this regime they describe smooth surfaces with long-range correlations and Hausdorf...
متن کاملConfining 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 کاملDeforming baryons into confining strings
We find explicit probe D3-brane solutions in the infrared of the Maldacena-Nuñez background. The solutions describe deformed baryon vertices: q external quarks are separated in spacetime from the remaining N − q. As the separation is taken to infinity we recover known solutions describing infinite confining strings in N = 1 gauge theory. We present results for the mass of finite confining strin...
