Decay widths of excited heavy mesons from quantum chromodynamics sum rules in the infinite mass limit
Source PublicationCHINESE PHYSICS LETTERS
KeywordChiral Perturbation-theory
AbstractThe widths for pionic decays of the lowest two excited doublets (0(+), 1(+)) and (1(+), 2(+)) of heavy mesons are studied with quantum Chromodynamics sum rules in the heavy quark effective theory. The interpolating currents used allow us to distinguish the two 1(+) states without contamination in the infinite mass Limit. The soft pion approximation is not used in the calculations.
