摘要:
First order power corrections to current matrix elements between heavy meson or LAMBDA-Q baryon states are shown to vanish at the zero recoil point to all orders in QCD. Five relations among the six form factors that parametrize the semileptonic decay LAMBDA(b)-->LAMBDA(c)e-nu-BAR are also demonstrated to exist to all orders in the strong coupling at order 1/m(Q). The O (alpha(s)(m(c))/m(c)) form factor relations are displayed.
