Probing the equivalence of chiral LCSRs in $D\to \pi e{\nu }_e$ decays and extraction of $|V_{cd}|$

Xiu-Fen Wang, Hai-Jiang Tian, Yin-Long Yang +2

In the paper, we have carried out research on the $D\to \pi$ decay process. We employ two different currents to study the $D\to \pi$ transition form factors (TFFs) by using the light-con…
