HIGHLIGHTS
- who: Lucha Wolfgang and colleagues from the InstitutAustria State University have published the research work: Charmed Mesons and Charmonia: Three-Meson Strong Couplings, in the Journal: (JOURNAL)
- what: The authors determine the meson wave-function parameters βηc,ψ of both charmonia such that the dispersion representation of their decay constants, fηc,ψ, reproduces the observed values.
SUMMARY
Revisiting the strong couplings of three mesons, each of which involves at least one charm quark, proves clear disaccord between quark-model and QCD sum-rule results. Three-meson strong couplings from relativistic constituent-quark . . .
