$\chi_{c0}(3915)$

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

was $X(3915)$

The $\chi_{c0}(3915)$ was originally seen by BELLE in its $\omega J/\psi$ decay mode and was produced in both B decays in CHOI 05 and $\gamma\gamma$ collisions in UEHARA 10. The $J^{PC}$ was determined to be $0^{++}$ by BABAR in LEES 12AD but this assignment was questioned by ZHOU 15C. In AAJ 20AI LHCb found the $D^{+}D^{-}$ decay mode of the $\chi_{c0}(3915)$ using B decays and determined its $J^{PC}$ to be $0^{++}$. Based on their compatible mass, width, and $J^{PC}$, we assume the state decaying to $\omega J/\psi$ and the state decaying to $D^{+}D^{-}$ are both the $\chi_{c0}(3915)$. See also the $\chi_{c2}(3930)$.

Due to the complexity of the $c\bar{c}$ 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 $2\sigma$ above zero, without regard to any peaking behavior in $\sqrt{s}$ or absence thereof.

$\chi_{c1}(4140)$

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

was $\chi(4140)$

This state shows properties different from a conventional $q\bar{q}$ state. A candidate for an exotic structure. See the review on non-$q\bar{q}$ states.

Seen by AALTONEN 09AH, ABAZOV 14A, CHATRCHYAN 14M, AAIJ 17C in $B^+ \to \chi_{c1}K^+, \chi_{c1} \to J/\psi\phi$, and by ABAZOV 15M separately in both prompt (4.7 $\sigma$) and non-prompt (5.6 $\sigma$) production in $p\bar{p} \to J/\psi\phi +$ anything. Not seen by SHEN 10 in $\gamma\gamma \to J/\psi\phi$ and ABLIKIM 15 in $e^+e^- \to \gamma J/\psi\phi$ at $\sqrt{s} = 4.23, 4.26, 4.36$ GeV.

Due to the complexity of the c<span style="text-decoration: overline">c</span> threshold region, in this listing, “seen” (“not seen”) means that a cross section for the mode in question has been measured at effective √s near this particle’s central mass value, more (less) than 2σ above zero, without regard to any peaking behavior in √s or absence thereof.

ψ(4230)

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

also known as Y(4230); was ψ(4260)

The original ψ(4260) (also known as Y(4260)) was observed by AUBERT,B 051 as a peak in the energy dependence of the $e^{+}e^{-} \rightarrow \pi^{+}\pi^{-}J/\psi$ cross section and was confirmed by HE 06B, YUAN 07, LEES 12AC, and LIU 13B in the same process. A higher-statistics analysis by ABLIKIM 17B revealed an asymmetry in the cross section and resulted in a shift of the peak position to a lower mass. The ψ(4260) was therefore renamed ψ(4230). The energy-dependent cross sections for $e^{+}e^{-}$ to other channels also exhibit peaks in the same mass region. The parameters corresponding to those peaks are also listed here, but the number of states in this region remains to be determined.

For details see the review on "Spectroscopy of mesons containing two heavy quarks."
