On the mass correction of heavy meson effective theory

Abstract

We derive the mass correction lagrangian of the heavy meson effective theory by using the projection operator method. The next leading order of the mass correction and the first order of the chiral expansion are given explicitely.We also consider the mass correction weak lagrangian of the heavy mesons. Finally, we give the $D^{\ast +}\to D^o{\pi }^{+}$ decay.
