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…

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…

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…

Dispersive analysis of the isospin breaking in the $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ and $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{0} I ¨ ^{-}$ decays

Jorgivan Morais Dias, Teng Ji, Xiang-Kun Dong +5

We analyze the latest LHCb data on the $I ¨ ^{+} I ¨ ^{-}$ spectrum in the isospin-violating $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ decay, based on dispersion theory to deal with the $I ¨ I ¨ $ final state…
