$\rho$-meson longitudinal leading-twist distribution amplitude revisited and the $D\to \rho$ semileptonic decay

Tao Zhong, Ya-Hong Dai, Hai-Bing Fu

Motivated by our previous work [Phys. Rev. D \textbf{104}, no.1, 016021 (2021)] on pionic leading-twist distribution amplitude (DA), we revisit $\rho$-meson leading-twist longitudinal…
