Characterize the properties of $D_{s}^{+}$ -meson decay constant and leptonic decays by using QCD sum rules within background field theory framework

Jian-Qi Chen, Ya-Xiong Wang, Hai-Bing Fu

The leptonic decays of the $D_{s}^{+}$ -meson have received considerable attention in recent years. In this work, we perform a precise calculation of the decay constant $f_{D_{s}^{+}}$ usin…

Scrutinizing lepton flavor universality and transition form factor correlation from charmed meson semileptonic decay into light strange vector $K^{*}$ meson

Sheng-Bo Wu, Dong Huang, Fang-Ping Peng +2

In this paper, we calculate the transition form factors (TFFs) $A_{1, 2} (q^{2})$ and $V (q^{2})$ of $D_{s}^{+} \to K^{* 0}$ decays by using the QCD light-cone sum rule (QCD LCSR) and construc…

Addressing the lightest $S$ -wave strange $K_{0}^{*} (700) / κ$ resonance in four-body semileptonic $B ˉ_{s}^{0} \to K^{0} π^{+} ℓ^{-} ν ˉ_{ℓ}$ decays

Dong Huang, Sheng-Bo Wu, Fang-Ping Peng +2

As the lightest strange scalar resonance, $K_{0}^{*} (700)$ (also called $κ$ ) has a large width and resides close to the $K π$ threshold, leading to a longstanding debate about its inter…

Quasi-four-body semileptonic decay $B ˉ^{0} \to a_{0} (1450)^{+} (\to π^{+} η) ℓ^{-} ν ˉ_{ℓ}$ within $a_{0} (1450)$ -resonance leading-twist LCDA under QCDSR

Ya-Lin Song, Yin-Long Yang, Yan-Ting Yang +4

The finite width of broad scalar resonances should be taken into account when relating semileptonic $B$ -meson transitions to experimentally reconstructable multihadron final states…

Probing the equivalence of chiral LCSRs in $D \to π e ν_{e}$ decays and extraction of $∣ V_{c d} ∣$

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

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

Nature of $K^{*} (1680)$ and $q q ˉ$ -hybrid mixing as the SU(3) partner of $η_{1} (1855)$ in the strange sector

Samee Ullah, Ye Cao, Ming-Xiao Duan +2

We presents an investigation of the $K^{*} (1680)$ state in its strong decays into two-body finial states within the flux-tube model and quark pair creation model. Since the charge co…

Probing the $γ γ^{*} \to η^{(')}$ Transition Form Factors with Newly Derived $η^{(')}$ -Meson Light-Cone Distribution Amplitudes

Dan-Dan Hu, Xing-Gang Wu, Yu-Jie Zhang +2

In the present work, we analyze the properties of the transition form factors (TFFs) for the $γ γ^{*} \to η^{(')}$ process, employing the $η^{(')}$ -meson light-cone distribut…
