Heavy-light scalar and axial-vector mesons decay constants and masses in QCD sum rule approach

Abstract

Many new results on heavy-light decay constants and masses have been obtaining recently thanks to advanced experimental techniques and searches. These experiments have learned a lot from states made of both light and heavy quarks. In the present work, the decay constants and masses of heavy-light mesons have been evaluated using QCD sum rules method. We compare obtained results of scalar and axial-vector mesons decay constants and masses with the predictions of the other approaches and experiments.
