Confining Classical Configurations
We construct a family of smooth, almost self-dual, non-thermalized SU(2) gauge field configurations, and measure the average of the fundamental, adjoint and spin 3 2 representation Wilson loops on them. We get area law in all three cases. We also study thermalised configurations at β = 2.325 after cooling. The ratio of string tension in the spin j representation over that in the fundamental, st...
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...
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 کاملMonopolonium in confining phase
Monopolonium is a monopole-antimonopole bound state, whose lifetime grows as the cube of the initial diameter. Such objects are important because their decay products can be observable. Apart from the monopolonium, it is believed that the existence of an epoch when the U(1) of the electromagnetism is spontaneously broken ensures the efficient annihilation of monopoles and antimonopoles in the U...
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...
