What is QCD Sum Rules for D* Decay Widths about?

The paper calculates the decay widths for D*-→D? and D*→Dπ using QCD sum rules in external vector and axial fields, finding reasonable agreement with experimental data. The total decay widths are significantly lower than the experimental upper limits, and the study also provides insights into the residue of D* mesons into vector currents. The analysis includes a detailed examination of the correlation functions and the impact of external fields on the decay processes.
