Strange hidden-charm pentaquark poles from $B^{-} \to J / ψ Λ p ˉ$

Satoshi X. Nakamura, Jia-Jun Wu

Recent LHCb data for $B^{-} \to J / ψ Λ p ˉ$ show a clear peak structure at the $Ξ_{c} D ˉ$ threshold in the $J / ψ Λ$ invariant mass ( $M_{J / ψ Λ}$ ) distribution. The LHCb's amplitude ana…

Global coupled-channel analysis of $e^{+} e^{-} \to c c ˉ$ processes in $s = 3.75 - 4.7$ GeV

S. X. Nakamura, X. -H. Li, H. -P. Peng +2

Recent high-precision $e^{+} e^{-} \to c c ˉ$ data from the BESIII and Belle are highly useful to understand vector charmonium ( $ψ$ ) pole structures and puzzling lineshapes due to the…

Three-body unitary coupled-channel approach to radiative $J / ψ$ decays and $η (1405/1475)$

S. X. Nakamura, Q. Huang, J. -J. Wu +3

Recent BESIII data on radiative $J / ψ$ decays from $\sim 1 0^{10}$ $J / ψ$ samples should significantly advance our understanding of the controversial nature of $η (1405/1475)$ . This mo…
