String point of view for heavy-light mesons

Yubing Dong, Qi-Fang Lü, Takayuki Matsuki

An approximate rotational symmetry of a heavy-light meson is viewed from a string picture. Using a simple string configuration, we derive a formula, $(M - m_{c})^{2} = π σ L$ , whose coeffici…

Low-lying charmed and charmed-strange baryon states

Bing Chen, Ke-Wei Wei, Xiang Liu +1

In this work, we systematically study the mass spectra and strong decays of $1 P$ and $2 S$ charmed and charmed-strange baryons in the framework of nonrelativistic constituent quark…

Revealing the inner structure of the newly observed $D_{2}^{*} (3000)$

Jun-Zhang Wang, Dian-Yong Chen, Qin-Tao Song +2

Stimulated by the recent observation of the $D_{2}^{*} (3000)$ , we study the decay behaviors of the $3 P$ and $2 F$ charmed mesons in the present work. By comparing the masses and deca…

Understanding $B^{-} \to X (3823) K^{-}$ via rescattering mechanism and predicting $B^{-} \to η_{c 2} (^{1} D_{2}) / ψ_{3} (^{3} D_{3}) K^{-}$

Hao Xu, Xiang Liu, Takayuki Matsuki

We study the observed $B^{-} \to X (3823) K^{-}$ decay via rescattering mechanism and show that this branching ratio is well reproduced by this mechanism. We further extend this t…

Approximate degeneracy of heavy-light mesons with the same $L$

Takayuki Matsuki, Qi-Fang Lü, Yubing Dong +1

Careful observation of the experimental spectra of heavy-light mesons tells us that heavy-light mesons with the same angular momentum $L$ are almost degenerate. The estimate is giv…
