Confining Strings at High Temperature
We show that the high-temperature behaviour of the recently proposed confining strings reproduces exactly the correct large-N QCD result, for a large class of trun-cations of the long-range interaction between surface elements.
متن کاملStrings and D-Branes at High Temperature
The thermodynamics of a gas of strings and D-branes near the Hagedorn transition is described by a coupled set of Boltzmann equations for weakly interacting open and closed long strings. The resulting distributions are dominated by the open string sector, indicating that D-branes grow to fill space at high temperature.
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 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...
