Nucleon electromagnetic form-factors in a minimal Gari-Krümpelmann model including the explicit two-pion continuum

Wulf Krümpelmann, Yong-Hui Lin, Ulf-G. Meißner

The Gari--Krümpelmann (GK) model provided one of the first semiphenomenological descriptions of the electromagnetic nucleon form-factors over a wide range of momentum transfer. It…

Understanding the near-threshold structures in $e^{+} e^{-}$ annihilation from a unified $N N ˉ$ -interaction perspective

Teng Ji, Ulf-G. MeiÃner

Near-threshold structures have been observed in the cross sections for $e^{+} e^{-} \to p p ˉ$ , $e^{+} e^{-} \to n n ˉ$ and several non-baryonic final states in the vicinity of the $N…

Pion axioproduction revisited

Cheng-Cheng Li, Tao-Ran Hu, Feng-Kun Guo +1

In this work, we extend the analysis of the pion axioproduction, $a N \to I ¨ N$ , to include the impact of the Roper resonance $N^{*} (1440)$ together the previously studied $I^ (1232)$ …

Short-range production of three bottom mesons

Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. MeiÃner

Previous investigations of the three-body dynamics of $B$ mesons have shown that no Efimov effect arises in systems composed of three $B$ and $B^{*}$ 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,…

Precise determination of the properties of $X (3872)$ and of its isovector partner $W_{c 1}$

Teng Ji, Xiang-Kun Dong, Feng-Kun Guo +2

We perform a simultaneous fit to BESIII data on $e^{+} e^{-} \to I^^{3} (D^{0} D ˉ^{0} I ¨ ^{0} / J / I ¨ I ¨ ^{+} I ¨ ^{-})$ and LHCb data on $B^{+} \to K^{+} (J / I ¨ I ¨ ^{+} I ¨ ^{-})$ to precisely determine the properties…
