1 Taking into account interference between the resonant and non-resonant $D\bar{D}$ production.

2 Reanalysis of data presented in BAI 02c. From a global fit over the center-of-mass energy region 3.7-5.0 GeV covering the $\psi(3770)$, $\psi(4040)$, $\psi(4160)$, and $\psi(4415)$ resonances. Phase angle fixed in the fit to $\delta = 0^\circ$.

3 Interference between the resonant and non-resonant $D\bar{D}$ production not taken into account.

4 From the joint analysis of the data on the $D\bar{D}$ and inclusive hadronic cross sections in the $\psi(3770)$ region from BaBar, Belle, BES-II, CLEO and KEDR.

CONSTRAINED FIT INFORMATION

An overall fit to the total width, a partial width, and 3 branching ratios uses 23 measurements and one constraint to determine 5 parameters. The overall fit has a $\chi^2 = 20.1$ for 19 degrees of freedom.

The following off-diagonal array elements are the correlation coefficients $\langle \delta\rho_i \delta\rho_j \rangle / (\delta\rho_i \delta\rho_j)$, in percent, from the fit to parameters $\rho_i$, including the branching fractions, $x_i \equiv \Gamma_i/\Gamma_{\text{total}}$. The fit constrains the $x_i$ whose labels appear in this array to sum to one.

¹From a fit to the e⁺e⁻ → J/ψX cross section at 3.645 and 3.891 GeV, with ψ(2S) and ψ(3770) masses, total widths and leptonic widths fixed to the values from the PDG 20. An alternative fit with an improved χ², corresponding to a significance of 5.3 σ, uses an additional resonance with a mass of 3766.2 ± 3.8 ± 0.4 MeV/c², a total width of 22.2 ± 5.9 ± 1.4 MeV, and Γ(e)·B(J/ψX) = 79.4 ± 85.5 ± 11.7 eV, possibly compatible with the results of ABLIKIM 08H.

$$ \chi_{c1}(3872) $$

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

also known as $\chi(3872)$

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.

First observed by CHOI 03 in $B \to K\pi^+\pi^-J/\psi(1S)$ decays as a narrow peak in the invariant mass distribution of the $\pi^+\pi^-J/\psi(1S)$ final state. Isovector hypothesis excluded by AUBERT 05B and CHOI 11.

AAIJ 13Q perform a full five-dimensional amplitude analysis of the angular correlations between the decay products in $B^+ \to \chi_{c1}(3872) K^+$ decays, where $\chi_{c1}(3872) \to J/\psi\pi^+\pi^-$ and $J/\psi \to \mu^+\mu^-$, which unambiguously gives the $J^{PC} = 1^{++}$ assignment under the assumption that the $\pi^+\pi^-$ and $J/\psi$ are in an S-wave. AAIJ 15AO extend this analysis with more data to limit D-wave contributions to < 4% at 95% CL.

See the review on "Spectroscopy of Mesons Containing Two Heavy Quarks."

²BHARDWAJ 11 reports $B(B^+ \to K^+ \chi_{c1}(3872)) \times B(\chi_{c1}(3872) \to \gamma\psi(2S)) < 3.45 \times 10^{-6}$ at 90% CL.

³AUBERT 09B reports $[\Gamma(\chi_{c1}(3872) \to \gamma\psi(2S))/\Gamma_{\text{total}}] \times [B(B^+ \to \chi_{c1}(3872) K^+)] = (9.5 \pm 2.7 \pm 0.6) \times 10^{-6}$ which we divide by our best value $B(B^+ \to \chi_{c1}(3872) K^+) = (2.3 \pm 0.6) \times 10^{-4}$. Our first error is their experiment's error and our second error is the systematic error from using our best value.
