Proposed mixing between $2 P$ and $1 F$ wave charmonia

Peng-Yu Sun, Tian-Le Gao, Zi-Long Man +1

The paper studies the mixing between the 2P and 1F charmonium states, finding that coupled‑channel effects can produce sizable mixing angles and predicting two‑photon and two‑gluon…

$T_{c s ˉ 0}^{a} (2900)$ , $T_{cs 0}^{*} (2900)^{0}$ , and other singly heavy tetraquark states

Zi-Long Man, Yu-Nan Liu, Yan-Rui Liu

We systematically study the mass spectra of $S$ -wave singly heavy tetraquark states $Qq q ˉ q ˉ$ ( $Q = c, b$ ; $q = u, d, s$ ) in a mass splitting model. We adopt the assumption that…

Assessing the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons

Zi-Long Man, Hao Zhou, Si-Qiang Luo +1

The Born-Oppenheimer approximation is widely used to investigate the properties of hydrogen-like systems and doubly heavy hadrons. However, the extent to which this approximation c…

Prospects for observing the missing $2 D$ and $1 F$ charmonium states around 4 GeV

Cheng-Xi Liu, Zi-Long Man, Tian-Le Gao +1

Our understanding of high-lying states within the charmonium family remains incomplete, particularly in light of recent observations of charmonium states at energies around 4 GeV.…

Is the $3 S$ - $2 D$ mixing strong for the charmonia $I ¨ (4040)$ and $I ¨ (4160)$ ?

Zi-Long Man, Si-Qiang Luo, Xiang Liu

In this work, we revisit the $3 S$ - $2 D$ mixing scheme for the charmonia $I ¨ (4040)$ and $I ¨ (4160)$ . We introduce a coupled-channel mechanism-distinct from the tensor-force contributi…

Coupled-channel study of $4 S$ - $3 D$ mixing dynamics in $I ¨ (4220)$ and $I ¨ (4380)$

Zi-Long Man, Si-Qiang Luo, Zi-Yue Bai +1

Among charmoniumlike $X Y Z$ states, the $I ¨ (4220)$ and $I ¨ (4380)$ states have emerged as key candidates for exploring the charmonium spectrum. In this work, we propose a $4 S$ - $3 D$ c…
