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 …
Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV
Xiang-Kun Dong, Vadim Baru, Leon von Detten +5
The spectrum of vector charmonium(-like) states in the 4.1\dash4.6~GeV energy region exhibits a long-standing tension between inclusive and exclusive measurements. While the inclus…
Neutrinoless double-beta decay of the resonance
Li-Ping He, Feng-Kun Guo, Ulf-G. Meißner +3
The subprocess is a key ingredient in the interpretation of nuclear neutrinoless double-beta decay. Intermediate resonances may provide additional enhancements…
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…
The Proton Charge Radius from Dimuon Photoproduction off the Proton
Yong-Hui Lin, Feng-Kun Guo, Ulf-G. Meißner
We investigate the feasibility of measuring the proton charge radius through dimuon photoproduction off a proton target. Our findings indicate that the Bethe-Heitler mechanism, whi…
Hints of the and Molecules in the Decay
Xiang-Kun Dong, Teng Ji, Feng-Kun Guo +2
The primary objective of this study is to investigate hadronic molecules of using a one-boson-exchange model, which incorporates exchanges of vector and pseudos…
Pion axioproduction revisited
Cheng-Cheng Li, Tao-Ran Hu, Feng-Kun Guo +1
In this work, we extend the analysis of the pion axioproduction, , to include the impact of the Roper resonance together the previously studied r…
Method for measuring the charge radii of charged hyperons from the time-like region
Yong-Hui Lin, Feng-Kun Guo, Ulf-G. Meißner
We propose a novel method for measuring the charge radii of charged stable hadrons, with which the first measurement of the charge radii of the and the is foreseen. The…
Decay behaviors of Pc hadronic molecules
Yong-hui Lin, Chao-wei Shen, Feng-kun Guo +1
The and states observed recently by LHCb experiment were proposed to be either or S-wave bound states of spin parity $J^P={\…
