1  Pole width obtained from a fit to a relativistic Breit-Wigner.
2  Neglecting interference between the ${{\mathit Z}_{{c}}{(3900)}}$ and other processes.
3  Measured in weak decays of ${{\mathit b}}$-flavored hadrons (nonprompt).
4  Pole width obtained from a fit to a Flatte-like formula.
5  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.
6  Superseded by ABLIKIM 2020N.
7  Superseded by ABLIKIM 2017J.
