@article{Simonov2015LeptonDC, title={Lepton decay constants of light mesons}, author={Yu. A. Simonov}, journal={Physics of Atomic Nuclei}, year={2015}, volume={79}, pages={444-454} }
A theory of lepton decay constants based on the path-integral formalism is given for chiral and vector mesons. Decay constants of the pseudoscalar and vector mesons are calculated and compared to other existing results.
