$a_{1} (1260)$ -meson longitudinal twist-2 distribution amplitude and the $D \to a_{1} (1260) ℓ^{+} ν_{ℓ}$ decay processes

Dan-Dan Hu, Hai-Bing Fu, Tao Zhong +2

In the paper, we investigate the moments $⟨ ξ_{2; a_{1}}^{∥; n} ⟩$ of the axial-vector $a_{1} (1260)$ -meson distribution amplitude by using the QCD sum rules approach under the…

Revisiting the production of $J / ψ + η_{c}$ via the $e^{+} e^{-}$ annihilation within the QCD light-cone sum rules

Long Zeng, Hai-Bing Fu, Dan-Dan Hu +3

We make a detailed study on the typical production channel of double charmoniums, $e^{+} e^{-} \to J / ψ + η_{c}$ , at the center-of-mass collision energy $s = 10.58$ GeV. The key componen…
