Recent Progress in Leptonic and Semileptonic Decays of Charmed Hadrons

Bai-Cian Ke, Jonna Koponen, Hai-Bo Li +1

We present a comprehensive review of purely leptonic and semileptonic decays of $D^{0 (+)}$ , $D_{s}^{+}$ , and charmed baryons (including $Λ_{c}^{+}$ , $Ξ_{c}$ and $Ω_{c}$ ). The precise studi…

Testing the light scalar meson as a non- $q q ˉ$ state in semileptonic $D$ decays

Yu-Kuo Hsiao, Shu-Qi Yang, Wen-Juan Wei +1

While the light scalar mesons ( $S_{0}$ ) are considered to be either ordinary $q q ˉ$ or exotic tetraquark states, we investigate the semileptonic decays $D \to S_{0} e^{+} ν_{e}$ , by takin…

Investigating $Z_{cs} (3985)$ and $Z_{cs} (4000)$ exotic states in $Λ_{b} \to Z_{cs}^{-} p$ decays

Yao Yu, Zhuang Xiong, Han Zhang +4

We study the $Z_{cs} (3985)$ and $Z_{cs} (4000)$ exotic states in the decays of $Λ_{b}$ baryons through a molecular scenario. In the final state interaction, the $Λ_b\to Λ_c^+ D_s^{(*)…

Determination of Spin-parity Quantum Numbers for the Narrow Structure Near the $p Λ ˉ$ Threshold in $e^{+} e^{-} \to p K^{-} Λ ˉ + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +593

A narrow structure in the $p Λ ˉ$ system near the mass threshold, named as $X (2085)$ , is observed in the process $e^{+} e^{-} \to p K^{-} Λ ˉ$ with a statistical significance greater th…

Muon mass correction in partial wave analyses of charmed meson semi-leptonic decays

Han Zhang, Bai-Cian Ke, Yao Yu +1

We derive the parameterization formula for partial wave analyses of charmed meson semi-leptonic decays with consideration of the effects caused by the lepton mass. As the proposed…

Photo-production of lowest $Σ_{1/ 2^{-}}^{*}$ state within the Regge-effective Lagrangian approach

Yun-He Lyu, Han Zhang, Neng-Chang Wei +3

Since the lowest $Σ^{*}$ state, with quantum numbers spin-parity $J^{P} = 1/ 2^{-}$ , is far from established experimentally and theoretically, we have performed a theoretical study o…
