$I^G(J^{PC})$ = $0^-(1^{- -})$

$4191$ $\pm5$ MeV

${{\mathit \psi}{(4160)}}$ WIDTH

${{\mathit \psi}{(4160)}}$ DECAY MODES

Due to the complexity of the ${{\mathit c}}{{\overline{\mathit c}}}$ threshold region, in this listing, ``seen'' (``not seen'') means that a cross section for the mode in question has been measured at effective $\sqrt {s }$ near this particle's central mass value, more (less) than 2${{\mathit \sigma}}$ above zero, without regard to any peaking behavior in $\sqrt {s }$ or absence thereof. See mode listing(s) for details and references.
