50 KORNICER 11 reports $[\Gamma(\Upsilon(3S) \to \gamma\chi_{b1}(1P))/\Gamma_{\text{total}}] \times [B(\chi_{b1}(1P) \to \gamma\Upsilon(1S))] = (5.38 \pm 1.20 \pm 0.95) \times 10^{-4}$ which we divide by our best value $B(\chi_{b1}(1P) \to \gamma\Upsilon(1S)) = (35.2 \pm 2.0) \times 10^{-2}$. Our first error is their experiment's error and our second error is the systematic error from using our best value.

52 HEINTZ 92, while unable to distinguish between different J states, measures $\sum_j B(\Upsilon(3S) \to \gamma\chi_{b,j}) \times B(\chi_{b,j} \to \gamma\Upsilon(1S)) = (1.7 \pm 0.4 \pm 0.6) \times 10^{-3}$ for J = 0,1,2 using inclusive $\Upsilon(1S)$ decays and $(1.2^{+0.4}_{-0.3} \pm 0.09) \times 10^{-3}$ for J = 1,2 using $\Upsilon(1S) \to \ell^+\ell^-\gamma$.

1. From a simultaneous fit to the $\Upsilon(nS)\pi^+\pi^-$, $n=1, 2, 3$, cross sections at 28 energy points within $\sqrt{s} = 10.6-11.05$ GeV, including the initial-state radiation at $\Upsilon(10860)$.

2. From a simultaneous fit to the $h_b(nP)\pi^+\pi^-$, $n=1, 2$, cross sections at 22 energy points within $\sqrt{s} = 10.77-11.02$ GeV to a pair of interfering Breit-Wigner amplitudes modified by phase space factors, with eight resonance parameters (a mass and width for each of $\Upsilon(10860)$ and $\Upsilon(11020)$, a single relative phase, a single relative amplitude, and two overall normalization factors, one for each $n$). The systematic error estimate is dominated by possible interference with a small nonresonant continuum amplitude.

3. From a fit to the dressed cross sections of AUBERT 09E by BaBar and SANTEL 16 by Belle above 10.68 GeV with a coherent sum of a continuum amplitude and three Breit-Wigner functions with constant widths.

4. From a fit to the total hadronic cross sections measured at 60 energy points within $\sqrt{s} = 10.82-11.05$ GeV to a pair of interfering Breit-Wigner amplitudes and two floating continuum amplitudes with $1/\sqrt{s}$ dependence, one coherent with the resonances and one incoherent, with six resonance parameters (a mass, width, and an amplitude for each of $\Upsilon(10860)$ and $\Upsilon(11020)$, one relative phase, and one decoherence coefficient).

5. Not including uncertain and potentially large systematic errors due to assumed continuum amplitude $1/\sqrt{s}$ dependence and related interference contributions.

6. From a simultaneous fit to the $\Upsilon(nS)\pi^+\pi^-$, $n=1, 2, 3$, cross sections at 25energy points within $\sqrt{s} = 10.6-11.05$ GeV to a pair of interfering Breit-Wigner amplitudesmodified by phase space factors, with fourteen resonance parameters (a mass, width, and threearamplitudes for each of $\Upsilon(10860)$ and $\Upsilon(11020)$, a single universal relativephase, and three decoherence coefficients, one for each $n$). Continuum contributions weremeasured (and therefore fixed) to be zero.
7 Superseded by MIZUK 19.

8 In a model where a flat non-resonant $b\bar{b}$-continuum is incoherently added to a second flat component interfering with two Breit-Wigner resonances. Systematic uncertainties not estimated.

9 The parameters of the Υ(11020) are fixed to those in AUBERT 09E.

10 In a model where a flat nonresonant Υ(1S, 2S, 3S)π⁺π⁻ continuum interferes with a single Breit-Wigner resonance.

11 In a model where a non-resonant $b\bar{b}$-continuum represented by a threshold function at $\sqrt{s}=2m_B$ is incoherently added to a flat component interfering with two Breit-Wigner resonances. Not independent of other AUBERT 09E results. Systematic uncertainties not estimated.

12 Assuming four Gaussians with radiative tails and a single step in R.

13 In a coupled-channel model with three resonances and a smooth step in R.

1 From a simultaneous fit to the Υ(nS)π⁺π⁻, n = 1, 2, 3, cross sections at 28 energy points within $\sqrt{s}=10.6-11.05$ GeV, including the initial-state radiation at Υ(10860).

2 From a simultaneous fit to the $\eta_b(nP)\pi^+\pi^-$, n = 1, 2 cross sections at 22 energy points within $\sqrt{s}=10.77-11.02$ GeV to a pair of interfering Breit-Wigner amplitudes modified by phase space factors, with eight resonance parameters (a mass and width for each of Υ(10860) and Υ(11020), a single relative phase, a single relative amplitude, and two overall normalization factors, one for each n). The systematic error estimate is dominated by possible interference with a small nonresonant continuum amplitude.

3 From a fit to the dressed cross sections of AUBERT 09E by BaBar and SANTEL 16 by Belle above 10.68 GeV with a coherent sum of a continuum amplitude and three Breit-Wigner functions with constant widths.

4 From a fit to the total hadronic cross sections measured at 60 energy points within $\sqrt{s}=10.82-11.05$ GeV to a pair of interfering Breit-Wigner amplitudes and two floating continuum amplitudes with $1/\sqrt{s}$ dependence, one coherent with the resonances and one incoherent, with six resonance parameters (a mass, width, and an amplitude for each of Υ(10860) and Υ(11020), one relative phase, and one decoherence coefficient).

5 Not including uncertain and potentially large systematic errors due to assumed continuum amplitude $1/\sqrt{s}$ dependence and related interference contributions.

6 From a simultaneous fit to the Υ(nS)π⁺π⁻, n = 1, 2, 3, cross sections at 25 energy points within $\sqrt{s}=10.6-11.05$ GeV to a pair of interfering Breit-Wigner amplitudes-modified by phase space factors, with fourteen resonance parameters (a mass, width, and threamplitudes for each of Υ(10860) and Υ(11020), a single universal relativephase, and three decoherence coefficients, one for each n). Continuum contributions weremeasured (and therefore fixed) to be zero.

7 Superseded by MIZUK 19.

8 In a model where a flat non-resonant $b\bar{b}$-continuum is incoherently added to a second flat component interfering with two Breit-Wigner resonances. Systematic uncertainties not estimated.

9 The parameters of the Υ(11020) are fixed to those in AUBERT 09E.

10 In a model where a flat nonresonant Υ(1S, 2S, 3S)π⁺π⁻ continuum interferes with a single Breit-Wigner resonance.

11 In a model where a non-resonant $b\bar{b}$-continuum represented by a threshold function at $\sqrt{s}=2m_B$ is incoherently added to a flat component interfering with two Breit-Wigner resonances. Not independent of other AUBERT 09E results. Systematic uncertainties not estimated.

12 Assuming four Gaussians with radiative tails and a single step in R.

13 In a coupled-channel model with three resonances and a smooth step in R.

The systematic error estimate is dominated by possible interference with a small nonresonant continuum amplitude.

OMITTED FROM SUMMARY TABLE
was $Z_{cs}(4000)$

Properties incompatible with a $q\bar{q}$ structure (exotic state). See the review on "Heavy Non-$q\bar{q}$ Mesons."

Seen by AAIJ 21E in $B^+ \rightarrow T_{c\bar{c}1}(4000)^+\phi$ with $T_{c\bar{c}1}(4000)^+ \rightarrow J/\psi K^+$ using an amplitude analysis of $B^+ \rightarrow J/\psi\phi K^+$ with a significance (accounting for systematic uncertainties) of 15 $\sigma$. The $J^P = 1^+$ assignment is favored with high significance. ABLIKIM 21G also reports a $J^P = 1^+ Z_{cs}$ state in this mass region using $e^+e^- \rightarrow K^+(D_S^*D^0 + D_S^*-D^0)$ with a significance of 5.3 $\sigma$. The incompatible values for the widths reported by AAIJ 21E and ABLIKIM 21G could either indicate the existence of two separate states or possibly be explained in a coupled channel model (see ORTEGA 21).

Charged $T_{c\bar{c}}(4020)$ seen by ABLIKIM 13X from $e^+e^- \to \pi^+\pi^- h_c(1P)$ at c.m. energy from 3.90 to 4.42 GeV as a peak in the invariant mass distribution of the $\pi^+\pi^- h_c(1P)$ system, and by ABLIKIM 14B from $e^+e^- \to (D^*\bar{D}^*)^{\pm\pi\mp}$ events in $(D^*\bar{D}^*)^{\pm}$ mass. A neutral $T_{c\bar{c}}(4020)$ seen by ABLIKIM 14P at three c.m. energies in the same range in $e^+e^- \to \pi^0\pi^0 h_c(1P)$ as a peak in the larger of the two masses recoiling against a $\pi^0$. ABLIKIM 15AA observes a 5.9 $\sigma$ signal in $(D^*\bar{D}^*)^0$ in $e^+e^- \to (D^*\bar{D}^*)^0$ events using collisions at two c.m. energies. Production rates and mass values support grouping neutral and charged $T_{c\bar{c}}(4020)$ together as manifestations of a single $I=1$ particle.
