Three-body unitary determination of the $f_{1} (1285)$ and $f_{1} (1420)$ pole positions

Tao-Ran Hu, Hai-Long Fu, Feng-Kun Guo +2

We study the $I^{G} (J^{P C}) = 0^{+} (1^{++})$ $K K ˉ I ¨ $ system in an infinite-volume three-body unitary framework, focusing on the pole content of the region of the $f_{1} (1285)$ and $f_1…

Threshold cusp effects to measure masses of radiatively decaying hadrons: The $B_{s 0}^{*}$ mass from the $I^¥ I ¨ $ spectrum

Hai-Long Fu, Xu Zhang, Feng-Kun Guo +3

Hadrons that decay predominantly into final states containing photons are notoriously difficult to detect at hadron colliders. Prominent examples are the yet-unobserved $B_{s 0}^{*}$ …

Exploring Efimov states in $D^{} D^{} D^{}$ and $D D^{} D^{*}$ three-body systems

Hai-Long Fu, Yong-Hui Lin, Feng-Kun Guo +4

The Efimov effect is an intriguing three-body quantum phenomenon. Searching for Efimov states within the realms of nuclear and hadronic physics presents a challenge due to the inhe…
