Amplitude structure of scattering in a Mandelstam variable representation
Xu Zhang, Feng-Kun Guo
We construct a dispersive representation of the relativistic scattering amplitude for three identical spinless particles in the -wave. The two-particle subenergy, inste…
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…
Pentaquarks in a dynamical coupled-channel approach of reaction
Xu Zhang
We construct a dynamical coupled-channel approach to photon-induced production to search for the trace of the pentaquarks . In this approach, the considered open-charm i…
