Abstract

Some very unusual features of the hadron structure functions, obtained in the generalized QCD sum rules, like the surprisingly strong difference between longitudinally and transversally polarized ρ mesons structure functions and the strong suppression of the gluon sea in longitudinally polarized ρ mesons are discussed. Also the problem of exact zero contribution of gluon condensates to pion and longitudinally polarized ρ meson quark distributions is discussed.
