摘要	The B-meson wavefunction has been studied with the help of the vacuum-to-meson matrix element of the non-local operators in the heavy quark effective theory. In order to obtain the Wandzura-Wilczek-type B-meson wavefunction, we solve the equations which are derived from the equation of motion of the light spectator quark in the B meson by using two different assumptions. Under the condition that omega(0) = 2 (Lambda) over bar, the solutions for the B-meson wavefunction in this paper agree well with the one obtained by directly taking the heavy quark limit m(b) -> infinity. Our results show that the equation of motion of the light spectator quark in the B meson can impose a strong constraint on the B-meson wavefunctions Psi(+/-)(omega, z(2)). Based on the obtained results, we claim that both its distribution amplitudes phi(B)(omega) and phi(B)(omega) are important for calculating the B meson decays. (c) 2005 Elsevier B.V.
