Abstract

The masses of excited heavy mesons are studied with sum rules in the heavy quark effective theory. A set of interpolating currents creating (annihilating) excited heavy mesons with arbitrary spin and parity are proposed and their properties are discussed. Numerical results at the leading order of the \cal O(1/m_Q) expansion are obtained for the lowest doublets (0⁺, 1⁺) and (1⁺, 2⁺).
