Abstract
We study semi- and non-leptonic decays of B and D mesons in the heavy- quark effective theory (HQET). By using the maximum likelihood method, it is shown that not only B decays but also D decays (D-0 --> K- (l) over bar v(l), D-0 --> K(-)pi(+) and K(-)rho(+)) are well described if O(<(Lambda)over bar>/m(c)) and O(<(Lambda)over bar>/m(s)) corrections are both taken into account.
