Abstract

The average kinetic energy of the heavy quark inside B or D meson is computed by means of the instantaneous Bethe-Salpeter method. We first solve the relativistic Salpeter equation and obtain the relativistic wave function and mass of 0- state, then we use the relativistic wave function to calculate the average kinetic energy of the heavy quark inside heavy meson of 0- state. We find that the relativistic corrections to the average kinetic energy of the heavy quark inside B or D meson are quite large and cannot be ignored. We estimate μπ2(=-λ 1)≈0.24(B0,B±), 0.20(D 0,D±), 0.33(Bs), 0.26(Ds), 0.83(Bc) and 0.62(ηc) GeV2.
