Relation between quark and gluon condensates from QCD sum rules

Abstract

A new relation between $\rho$-meson mass, weak $\pi$-meson decay constant, quark and gluon condensates is derived from the QCD sum rules. As a byproduct an explanation for the dominance of $\rho \rho$-decay for the $f_0(1370)$-meson is proposed.
