Probing $D_{s}^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ semileptonic decay within LCSR under chiral heavy quark effective field theory

Ruiyu Zhou, Hai-Bing Fu, Yi Zhang +1

Motivated by the successful application of Heavy Quark Effective Field Theory in describing decays from heavy to light mesons, this work explores its applicability to the semilepto…

Footprint in fitting $B \to D$ vector form factor and determination for $D$ -meson leading-twist LCDA

Sheng-Bo Wu, Hai-Jiang Tian, Yin-Long Yang +3

In this paper, we fit the $B \to D$ vector transition form factor (TFF) by using the data measured by \textsl{BABAR} and Belle Collaborations within Monte Carlo (MC) method. Meanwhi…

$B_{(s)} \to S (a_{0} (1450), K_{0}^{*} (1430), f_{0} (1500))$ helicity form factors within QCD light-cone sum rules

Yi Zhang, Wei Cheng, Jia-Wei Zhang +3

In this paper, we investigate the helicity form factors (HFFs) of the $B_{(s)}$ -meson decay into a scalar meson with a mass larger than 1~GeV, {\it i.e.,} $B \to a_{0} (1450)$ , $B_{(s…

The ratio $R (D_{s})$ for $B_{s} \to D_{s} ℓ ν_{ℓ}$ by using the QCD light-cone sum rules within the framework of heavy quark effective field theory

Yi Zhang, Tao Zhong, Hai-Bing Fu +3

In the paper, we study the $B_{s} \to D_{s}$ transition form factors by using the light-cone sum rules within the framework of heavy quark effective field theory. We adopt a chiral curr…
