Precocious scaling and nonperturbative effects in QCD

Zeitschrift für Physik C Particles and Fields, 1983
The onset of nonperturbative effects in QCD is studied in two ways: (1) by means of the nonvanishing vacuum expectation value of 〈g2F2〉 introduced by Shifman, Vainshtein and Zakharov; (2) using a finite energy sum rule (FESR) for the renormalization group function β.

Nonperturbative region of effective strong coupling

, 2013
In the framework of Poincar covariant quark model the behavior of running coupling constant $ _{s}\left(Q^{2}\right)$ is considered in $Q < 1 \mbox{GeV}$ region. An analysis was carried out for pseudoscalar and vector mesons with lepton decay constants, masses (obtained from model dependent) and nucleon spin rules required to match their ...

DVCS via color dipoles: Nonperturbative effects

, 2008
We study the DVCS amplitude within the color dipole approach. The light-cone wave function of a real photon is evaluated in the instanton vacuum model. Our parameter free calculations are able to describe H1 data, both the absolute values and the $t$-dependences, at medium-high values of $Q^{2}$.
