Decay Widths of Excited Heavy Mesons From QCD Sum Rules at the Leading Order of HQET
General Physics: Statistical and Quantum Mechanics, Quantum Information, etc.
The widths for pionic decays of lowest two excited doublets (0+, 1+) and(1+, 2+) of heavy mesons are studied with QCD sum rules in the leading order of heavy quark effective theory. The ambiguity due to presence of two distinct 1+ states are solved. The soft pion approximation is not used.
