Gluon Field Strength Correlation Functions within a Constrained Instanton Model
A. E. Dorokhov, S. V. Esaibegyan, A. E. Maximov +1
We suggest a constrained instanton (CI) solution in the physical QCD vacuum which is described by large-scale vacuum field fluctuations. This solution decays exponentially at large…
Virtualities of Quarks and Gluons in QCD Vacuum and Nonlocal Condensates within Single Instanton Approximation
A. E. Dorokhov, S. V. Esaibegyan, S. V. Mikhailov
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 valu…
Multi-Instanton Effects in QCD Sum Rules for the Pion
A. E. Dorokhov, S. V. Esaibegyan, N. I. Kochelev +1
Multi-instanton contributions to QCD sum rules for the pion are investigated within a framework which models the QCD vacuum as an instanton liquid. It is shown that in singular gau…
Pseudoscalar and vector correlations in instanton vacuum model
S. V. Esaibegyan, S. N. Tamaryan
It is shown, that the correct account of quark interaction generated by instanton medium gives the possibility of description on the same ground of both pseudoscalar channel and lo…
