QCD sum rules for radially excited heavy-light mesons — •Patrick Gelhausen, Alexander Khodjamirian, Alexei A. Pivovarov, and Denis Rosenthal — Universität Siegen, Theoretische Physik 1, 57068 Siegen

In the last decades QCD sum rules proved to be a reliable tool for the determination of QCD parameters such as quark masses or vacuum condensates as well as for the calculation of various hadronic matrix elements relevant for flavour physics.
In addition to the decay constants of ground-state heavy-light mesons B(*) and D(*), the phenomenological description of the heavy-light form factors demands knowledge of decay constants of radially excited heavy-light states. Modifying the QCD sum rule method we extract these constants for the first radial excitations with the quantum numbers of B(*) and D(*).
