Heavy Quarkonia: Wilson Area Law, Stochastic Vacuum Model and Dual QCD
The QQ̄ semirelativistic interaction in QCD can be simply expressed in terms of the Wilson loop and its functional derivatives. In this approach we present the QQ̄ potential up to order 1/m2 using the expressions for the Wilson loop given by the Wilson Minimal Area Law (MAL), the Stochastic Vacuum Model (SVM) and Dual QCD (DQCD). We confirm the original results given in the different frameworks a...
متن کاملStochastic Vacuum Model and Dual Theory: a Comparison in the Context of the Heavy Quarkonia Potential
where W (Γ) is the Wilson loop over the closed path Γ including the quark and antiquark trajectories Γ1 and Γ2. The double bracket means the average on the gauge fields in presence of the Wilson loop. A path ordering is understood where ambiguities in the ordering of the colour matrices can arise. The 1/m order terms in 1 are of two types, velocity dependent VVD and spin dependent VSD. Therefor...
متن کاملSuper-heavy Quarkonia as a probe of the QCD Vacuum
The phenomenon of gluon condensation is under vital discussion since more than fifteen years now [1]. The gluon condensate is an important quantity not only in the sum rule approach but also in high-energy hadron scattering and phenomenological models of confinement. Despite many indications of a non-trivial vacuum the quantitative picture is still vague [3]. Quarkonia are the simplest hadronic...
متن کاملString breaking in QCD: dual superconductor vs. stochastic vacuum model
Abstract: Effects of dispersion of the chromoelectric field of the flux tube on the stringbreaking distance are studied. The leading-order correction is shown to slightly diminish the result following from the Schwinger formula. Instead, accounting for corrections of all orders might result, at certain values of the Landau-Ginzburg parameter, in an increase of the string-breaking distance up to...
متن کاملQcd Potential Model for Light-heavy Quarkonia and the Heavy Quark Effective Theory
We have investigated the spectra of light-heavy quarkonia with the use of a quantum-chromodynamic potential model which is similar to that used earlier for the heavy quarkonia. An essential feature of our treatment is the inclusion of the one-loop radiative corrections to the quark-antiquark potential, which contribute significantly to the spin-splittings among the quarkonium energy levels. Unl...
