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…

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…

Investigation for $D^{+} \to π^{+} ν ν ˉ$ decay process within QCDSR approach

Yu Chen, Hai-Bing Fu, Tao Zhong +2

In the paper, we investigate the charmed meson rare decay process $D^{+} \to π^{+} ν ν ˉ$ by using QCD sum rules approach. Firstly, the pion twist-2 and twist-3 distribution amplitude…
