Finite-range EFT for the strength distribution of He
Matthias Göbel, Hans-Werner Hammer, Daniel R. Phillips
Halo effective field theory (Halo EFT) is a powerful tool to describe halo nuclei and predict low-energy observables with quantified uncertainties. However, in the case that there…
Short-range production of three bottom mesons
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. MeiÃner
Previous investigations of the three-body dynamics of mesons have shown that no Efimov effect arises in systems composed of three and mesons. This implies that the pr…
Model-independent mass determination of near-threshold states from short-range production
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. MeiÃner
We propose a novel observable for the precision measurements of a wide class of near-threshold dimer states: the short-range production rate of a dimer--spectator two-body system,…
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…
Baryon Form Factors
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. MeiÃner +1
We review the status of baryon form factors with a special focus on the nucleon electromagnetic form factors which are known best. First, we give an introduction into the dispersiv…
