O(1 M(Q)) CORRECTIONS TO MASSES OF EXCITED HEAVY MESONS FROM QCD SUM-RULES/

The O(1/m(Q)) corrections to masses of excited heavy mesons are studie d with sum rules in the heavy quark effective theory. Numerical result s for the matrix elements of the heavy quark kinetic energy operator K and chromomagnetic interaction operator S are obtained for the lowest excited doublets (0(+),1(+)) and (1(+),2(+)).
