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 $K_{0}^{*} (700) / I^º$ 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…

$a_{0} (1450)$ -state twist-2 light-cone distribution amplitude moments within QCD sum rules and its implication in $B ˉ^{0} \to a_{0} (1450)^{+} ℓ^{-} I^ˉ ½_{ℓ}$ decays

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

Based on longstanding puzzle for the structure of light scalar meson, it is meaningful to make a deep research for its property in different decay processes especially in the botto…

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 $D^{+} \to I ¨ ℓ^{+} I^½_{ℓ}$ …

Probing the equivalence of chiral LCSRs in $D \to I ¨ e I^½_{e}$ 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 I ¨ $ decay process. We employ two different currents to study the $D \to I ¨ $ transition form factors (TFFs) by using the light-c…
