String Theory and Quark Confinement
This article is based on a talk given at the “Strings ’97” conference. It discusses the search for the universality class of confining strings. The key ingredients include the loop equations, the zigzag symmetry, the non-linear renormalization group. Some new tests for the equivalence between gauge fields and strings are proposed.
متن کاملStrange quark matter attached to string cloud in general scalar tensor theory of gravitation
Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...
متن کاملQuark confinement and the bosonic string
Using a new type of simulation algorithm for the standard SU(3) lattice gauge theory that yields results with unprecedented precision, we confirm the presence of a γ/r correction to the static quark potential at large distances r, with a coefficient γ as predicted by the bosonic string theory. In both three and four dimensions, the transition from perturbative to string behaviour is evident fro...
متن کاملGeneralization of the Quark-confining String*
It is natural to generalize the quark-confining string model by introducing additional terms coming from the Riemann curvature tensor. For simplicity, only terms linear in the Riemann tensor are considered. In the absence of quark fields, such terms are trivial (as in two dimensional gravity). In the presence of quark fields, embedding of the string in four dimensional Minkowski . space renders...
متن کاملQuark mass correction to the string potential.
A consistent method for calculating the interquark potential generated by the relativistic string with massive ends is proposed. In this approach the interquark potential in the model of the Nambu–Goto string with point–like masses at its ends is calculated. At first the calculation is done in the one–loop approximation and then the variational estimation is performed. The quark mass correction...
