Abstract: | In this paper distribution amplitudes of pseudoscalar and vector nonrelativistic mesons are considered. Using equations of
motion for the distribution amplitudes, relations are derived which allow one to calculate the masses of nonrelativistic pseudoscalar
and vector meson if the leading twist distribution amplitudes are known. These relations can be also rewritten as relations
between the masses of nonrelativistic mesons and infinite series of QCD operators, what can be considered as an exact version
of Gremm-Kapustin relation in NRQCD. |
