This work makes a significant step forward by completing the effort begun in

"Heavy+light pseudoscalar meson semileptonic transitions, Zhen-Ni Xu (徐珍妮) et al., NJU-INP 040/21, arXiv:2103.15964 [hep-ph], Eur. Phys. J. C 81 (2021) 1105/1-16 " 

and delivering the first single-framework unified treatment of the semileptonic decays of light+light, heavy+light, and heavy+heavy mesons to both pseudoscalar and vector meson final states.  This is not a QCD study, but it does incorporate the necessary basics; namely, emergent hadron mass and the way it is modulated/complemented by Higgs-boson effects.  Where comparisons are possible, this general treatment yields results that are at least equal to those obtained in system-tuned/specific approaches, and the latter include simulations of lattice-QCD.
