Improved covariant analysis of $B_{c}^{+} \to χ_{c 1} (n P)$ decays and implications for the nature of $χ_{c 1} (3872)$

Shi-Hang Zhang, Jia-Yi Zheng, Wei Li +5

We study the weak decays $B_{c}^{+} \to χ_{c 1} (n P) ℓ^{+} ν_{ℓ}$ and $B_{c}^{+} \to χ_{c 1} (n P) X$ (n=1,2,3) within the Bethe-Salpeter formalism, treating $χ_{c 1} (3872)$ as the conventional $χ…

Meson properties and symmetry emergence based on the deep neural network

Xin Tong, Wei Feng, Weiwei Xu +3

As a key property of hadrons, the total width is quite difficult to obtain in theory due to the extreme complexity of the strong and electroweak interactions. In this work, a deep…

Strong decays of $P_{I ¨} ^{N} (4440)^{+}$ and $P_{I ¨} ^{N} (4457)^{+}$ within the Bethe-Salpeter framework

Qiang Li, Chao-Hsi Chang, Xin Tong +3

By combining the effective Lagrangian and Bethe-Salpeter framework, we studied the mass spectra, wave functions, and strong decay widths of the two pentaquark states $P_Ï^N(4440)^…
