Clarifying the puzzling mass shift of the $ψ (4160)$ via a reanalysis of $R$ -value data with unquenched charmonium spectroscopy

Tian-Cai Peng, Xiang Liu

The long-standing upward shift of the extracted $ψ (4160)$ mass, from about $4.16$ ~GeV to $4.19$ ~GeV in later analyses, remains a puzzling issue in charmonium spectroscopy. In our p…

Basis light-front quantization for the $Λ_{b}$ and $Σ_{b}$ baryons

Lingdi Meng, Tian-Cai Peng, Zhi Hu +6

Within the basis light-front quantization framework, we compute the masses and light-front wave functions of the $Λ_{b}$ baryon and its isospin triplet counterparts $Σ_{b}^{+}$ , $Σ_{b}^{0}$ ,…

Reevaluating the $ψ (4160)$ Resonance Parameter Using $B^{+} \to K^{+} μ^{+} μ^{-}$ Data in the Context of Unquenched Charmonium Spectroscopy

Tian-Cai Peng, Zi-Yue Bai, Jun-Zhang Wang +1

A puzzling phenomenon, where the measured mass of the $ψ (4160)$ is pushed higher, presents a challenge to current theoretical models of hadron spectroscopy. This study suggests tha…

How higher charmonia shape the puzzling data of the $e^{+} e^{-} \to η J / ψ$ cross section

Tian-Cai Peng, Zi-Yue Bai, Jun-Zhang Wang +1

Recently, the BESIII collaboration performed a precise measurement of the $e^{+} e^{-} \to η J / ψ$ cross section. It is puzzling that the resonance parameters of the reported $Y (4230)$ sho…

Transverse momentum structure of strange and charmed baryons: a light-front Hamiltonian approach

Zhimin Zhu, Tiancai Peng, Zhi Hu +5

Under the basis light-front quantization framework, we investigate the leading-twist transverse-momentum-dependent parton distribution functions (TMDs) for $Λ$ and $Λ_{c}$ baryons, t…

Basis light-front quantization approach to $Λ$ and $Λ_{c}$ and their isospin triplet baryons

Tiancai Peng, Zhimin Zhu, Siqi Xu +4

We obtain the masses, the electromagnetic properties, and the parton distribution functions (PDFs) of $Λ$ , $Λ_{c}$ , and their isospin triplet baryons, i.e, $Σ^{0}$ , $Σ^{+}$ , $Σ^{-}$ and $Σ…
