Estimates of higher – dimensional vacuum condensates from the instanton vacuum
نویسندگان
چکیده
We calculate the values of non-factorizable dimension{7 vacuum condensates in the instanton vacuum. We comment on a method, recently proposed by Oganesian, to estimate the dimension{7 condensates by factorization of dimension{10 condensates in various inequivalent ways. The instanton estimates could be used to analyze the stability of QCD sum rules with increasing dimensions. PACS: 12.38.Lg, 11.15.Kc, 11.15.Pg, 14.20.Dh

Virtualities of Quarks and Gluons in Qcd Vacuum and Nonlocal Condensates within Single Instanton Approximation
We calculate the lowest-dimensional nonlocal quark and gluon condensates within the single instanton approximation of the instanton liquid model. As a result, we determine the values of average virtualities of quarks λq and gluons λ 2 g in the QCD vacuum and obtain parameterless predictions for the ratio λg/λ 2 q = 12/5, and for some ratios of different vacuum condensates of higher dimensions. ...
متن کاملPath 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 کاملDynamical Higgs Mechanism without Elementary Scalars: A Lesson from Instantons
The generation of gauge–dependent fermion vacuum condensates in Yang– Mills theory would dynamically break the gauge symmetry and thus provide an alternative to the Higgs mechanism in unified theories. We explore a simple example: instanton-induced quark pair (diquark) condensation in QCD with 2 flavors and Nc colors. We do find diquark condensates in the vacuum, but only for Nc = 2, where they...

متن کاملNonlocal Condensates and Current-current Correlators within the Instanton Liquid Model
The non-perturbative vacuum of QCD is densely populated by long wave fluctuations of gluon and quark fields. The order parameters of this complicated state are characterized by the vacuum matrix elements of various singlet combinations of quark and gluon fields, condensates: 〈: q̄q :〉, 〈 : F a μνF a μν : 〉 , 〈 : q̄(σμνF a μν λ 2 )q : 〉 , etc. The nonzero quark condensate 〈: q̄q :〉 is responsible f...
