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 $K_{0}^{*} (700) / I^º$ resonance in four-body semileptonic $B ˉ_{s}^{0} \to K^{0} I ¨ ^{+} ℓ^{-} I^ˉ ½_{ℓ}$ decays

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

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

Non-perturbaitve effects for the isoscalar light vector $I ¨ $ -meson in charmed meson semileptonic decays

Yin-Long Yang, Fang-Ping Peng, Yan-Ting Yang +2

Motivated by the renewed attention from the recent BESIII experiment on the semileptonic decay $D \to V ℓ I^½_{ℓ}$ , we investigate semileptonic decay $D^{+} \to I ¨ ℓ^{+} I^½_{ℓ}$ …

Exploring the exclusive decay $B^{+} \to I ¨ ℓ^{+} I^½$ with light-cone sum rules

Yin-Long Yang, Ya-Lin Song, Fang-Ping Peng +3

In this paper, we calculate the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{u b} ∣$ by the semileptonic decay $B^{+} \to I ¨ ℓ^{+} I^½$ . For the transition form factors (TFFs) $A_{1} (q^{2})$ …
