Analysis of scalar meson decays reveals key decay constants in QCD frameworks, indicating alignment with measurements.

The calculated decay constant for the f0(980) is 0.386±0.009 GeV, supporting theoretical frameworks.
Transition form factor results yield f+(0) = 0.51-0.024+0.027 in the large-recoil region, crucial for decay studies.
Using QCD light-cone sum rules, we also predict differential decay widths and branching fractions accurately.
Predictions align closely with BESIII Collaboration measurements, validating our theoretical approaches.
