Three-body unitary determination of the and pole positions
Tao-Ran Hu, Hai-Long Fu, Feng-Kun Guo +2
We study the system in an infinite-volume three-body unitary framework, focusing on the pole content of the region of the and $f_1…
Threshold cusp effects to measure masses of radiatively decaying hadrons: The mass from the 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 …
Exploring Efimov states in and 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…
Three-body universality in the B meson sector
Yong-Hui Lin, Erik Wilbring, Hai-Long Fu +2
The charged exotic mesons Z_b(10610) and Z'_b(10650) observed by the Belle collaboration in 2011 are very close to the B* Bbar and B* Bbar* thresholds, respectively. This suggests…
