dc.description.abstract	Analytic properties of the nonperturbative running expansion parameter in quantum chromodynamics which is appeared within variational perturbation theory are investigated. We argue that a requirement of the Kallen-Lehmann analyticity allows one to define a variational parameter the value of which is agreed well with nonperturbative data coming from the meson spectroscopy.	ru_RU
