Nonperturbative QCD Vacuum Effects in Nonlocal Quark Dynamics
نویسنده
چکیده
A straightforward calculation reveals the essentially nonlocal character of the leading heavy QQ̄ interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum. In light of this quarkonium spin splitting ratio predictions which have supported the scalar confinement ansatz are reconsidered as a specific example of possible consequences for spectroscopy.

Path Dependence of the Quark Nonlocal Condensate within the Instanton Model
The nonlocal vacuum condensates or vacuum correlators describe the distribution of quarks and gluons in the nonperturbative QCD vacuum [1]. Physically, it means that vacuum quarks and gluons can flow through the vacuum with nonzero momentum. Nonlocal condensates play an important role in hadron physics. The nonlocal properties of the vacuum condensates are of principle importance in the study o...
متن کاملSelf-consistent Gaussian model of nonperturbative QCD vacuum
We show that the minimal Gaussian model of nonlocal vacuum quark and quark-gluon condensates in QCD generates the non-transversity of vector current correlators. We suggest the improved Gaussian model of the nonperturbative QCD vacuum, which respects QCD equations of motion and minimizes the revealed gauge-invariance breakdown. We obtain the refined values of pion distribution amplitude (DA) co...

The leading nonperturbative QCD corrections to the one gluon exchange quark-quark, quark-antiquark and q ¯ q pair-excitation potentials are derived by using a covariant form of nonlocal two-quark and two-gluon vacuum expectation values. Our numerical calculation indicates that the correction of quark and gluon condensates to the quark-antiquark potential improves the heavy quarkonium spectra to...
متن کاملNonperturbative dynamics in the colour – magnetic QCD vacuum
In the deconfinement phase of QCD quarks and gluons interact with the dense stochastic colour–magnetic vacuum. We consider the dynamics of quarks in this deconfinement phase using the Field Correlators Method and derive an effective nonperturbative interquark potential, in addition to the usual perturbative short–ranged interaction. We find the resulting angular–momentum–dependent interaction t...
