1
Measured in weak decays of ${{\mathit b}}$-flavored hadrons (nonprompt).
|
2
The signal of the ${{\mathit Z}_{{c}}{(3900)}}$ is correlated with a parent ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ system in the invariant mass range $4.2 - 4.7$ GeV.
|
3
Neglecting interference between the ${{\mathit Z}_{{c}}{(3900)}}$ and non-resonant continuum.
|
4
For $\mathit M{}^{2}$( ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) $<$ 0.65 GeV${}^{2}$. Obtained by analyzing CLEO-c data but not authored by the CLEO Collaboration.
|
5
Pole mass obtained from a fit to a Flatte-like formula.
