Reviving the energy-dependent partonic structure of $f_{0} (980)$ via two-pion distribution amplitudes

Shan Cheng, Ling-yun Dai, Jian-ming Shen +1

We present a novel framework for analyzing four-body semileptonic weak decays, performing the first high-twist analysis of the $D_{s} \to [I ¨ I ¨ ]_{S}$ form factors usi…

QCD analysis of $B \to I ¨ I ¨ $ form factors and the $∣ V_{u b} ∣$ extraction from $B_{l 4}$ decays

Shan Cheng

The $B_{l 4}$ decays offer an independent method for determining the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{u b} ∣$ , with a QCD analysis of the underlying $B \to ÏÏ…
