Classical and spin polarizabilities of singly heavy baryons within heavy baryon chiral perturbation theory

Zi-Jun Li, Zhan-Wei Liu, Ping Chen

We present a systematic study of the electromagnetic and spin polarizabilities of spin-1/2 singly charmed baryons at $O (p^{4})$ within the framework of heavy baryon chiral…

Electromagnetic probes revealing the inner structure of the $Λ_{c} (2940)$

Ping Chen, Zi-Le Zhang, Yu Zhuge

The $Λ_{c} (2940)$ , an open-charm baryon discovered in 2006, has sparked interest due to its ``low mass puzzle'', paralleling the $X (3872)$ in the charmoniumlike sector. Both states c…

Masses and radiative decay widths of the $D_{s 0}^{*} (2317)$ and $D_{s 1}^{'} (2460)$ and their bottom analogs

Zi-Le Zhang, Zhan-Wei Liu, Si-Qiang Luo +2

We study the mass spectra and radiative decays of $D_{s 0}^{*} (2317)$ and $D_{s 1}^{'} (2460)$ in an unquenched framework. In addition to coupled channel effects between the $c\bar…
