1 The $B_s^0$ mesons are reconstructed via the decays $B_s^0 \to J/\psi \phi$ and $B_s^0 \to D_s^+ \pi^+$. The third uncertainty includes systematic (±8) and imprecise knowledge of the branching fractions (±3).

Updated March 2024.

<figure><img src="image_644.png" /></figure>

The level scheme of meson states containing a minimal quark content of $c\bar{c}$ and having $S = C = B = 0$. The name of a state is determined by its quantum numbers $I^G, J^{PC}$ (see the review “Naming Scheme for Hadrons”). States included in the Summary Tables are shown with solid lines; selected states not in the Summary Tables, but with assigned quantum numbers, are shown with dotted lines. The arrows indicate the most dominant hadronic transitions. Single photon transitions, including $\psi(nS) \to \gamma\eta_c(mS)$, $\psi(nS) \to \gamma\chi_{cJ}(1P)$, and $\chi_{cJ}(1P) \to \gamma J/\psi$, are omitted for clarity. For orientation, the location of the thresholds related to a pair of ground state open charm mesons is indicated in the figure. The $J^P$ of $T_{cc}(4020)$ is not established. Decays to open flavour final states are not shown in the figure.

4 AAIJ 15BI reports $m_{J/ψ} - m_{\eta_c(1S)} = 114.7 \pm 1.5 \pm 0.1$ MeV from a sample of $\eta_c(1S)$ and $J/ψ$ produced in b-hadron decays. We have used current value of $m_{J/ψ} = 3096.900 \pm 0.006$ MeV to arrive at the quoted $m_{\eta_c(1S)}$ result.

5 Taking into account an asymmetric photon lineshape.

FIT INFORMATION

A multiparticle fit to $\eta_c(1S)$, $J/\psi(1S)$, $\psi(2S)$, $h_c(1P)$, and $B^\pm$ with the total width, 10 combinations of partial widths obtained from integrated cross section, and 38 branching ratios use 113 measurements to determine 19 parameters. The overall fit has a $\chi^2 = 184.6$ for 94 degrees of freedom.

The following off-diagonal array elements are the correlation coefficients $\langle\delta p_i \delta p_j\rangle/(\delta p_i \delta p_j)$, in percent, from the fit to parameters $p_i$, including the branching fractions, $x_i \equiv \Gamma_i/\Gamma_{\text{total}}$.

1 Supersedes AULCHENKO 03.

2 Reanalysis of ZHOLENTZ 80 using new electron mass (COHEN 87) and radiative corrections (KURAEV 85).

3 Mass central value and systematic error recalculated by us according to Eq. (16) in ARMSTRONG 93B, using the value for the $\psi(2S)$ mass from AULCHENKO 03.

4 From a sample of $\eta_c(1S)$ and $J/\psi$ produced in b-hadron decays. Systematic uncertainties not estimated.

5 Supersedes by ARTAMONOV 00.

6 From a simultaneous fit to e<sup>+</sup>e<sup>-</sup>, μ<sup>+</sup>μ<sup>-</sup> and hadronic channels assuming Γ(e<sup>+</sup>e<sup>-</sup>) = Γ(μ<sup>+</sup>μ<sup>-</sup>).

¹Based on the same dataset as ANASHIN 18A and correlated to the values reported there

²Calculated by us from the reported values of Γ(e⁺e⁻)×B(μ⁺μ⁻) using B(e⁺e⁻) = (5.94 ± 0.06)% and B(μ⁺μ⁻) = (5.93 ± 0.06)%.

³The initial-state radiation correction reevaluated by ANDREOTTI 07 in its Ref. [4].

⁴Using data from COFFMAN 92, BALDINI-CELIO 75, BOYARSKI 75, ESPOSITO 75B, BRANDELIK 79.

⁵Using Γ(e⁺e⁻) from ANASHIN 18A and B(J/ψ(1S) → e⁺e⁻) = (5.971 ± 0.032)% from PDG 16.

⁶Superseded by ANASHIN 20 that is based on the same dataset.
