ψ(4360)

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

also known as Y(4360); was X(4360)

This state shows properties different from a conventional qγ state. A candidate for an exotic structure. See the review on non-qγ states.

Seen in radiative return from e⁺ e⁻ collisions at √s = 9.54–10.58 GeV by AUBERT 07S, WANG 07D, and LEES 14F. See also the review on "Spectroscopy of mesons containing two heavy quarks."

$\psi(4660)$

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

also known as Y(4660); was X(4660)

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 in radiative return from $e^+e^- \to \sqrt{s} = 9.54-10.58$ GeV by WANG 07D. Also obtained in a combined fit of WANG 07D, AUBERT 07S, and LEES 14F. See also the review on "Spectroscopy of mesons containing two heavy quarks."

## $b\bar{b}$ MESONS
(including possibly non-$q\bar{q}$ states)

Updated March 2024.

<figure><img src="image_693.png" /></figure>

The level scheme of meson states containing a minimal quark content of $b\bar{b}$ 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; those requiring confirmation are shown with dotted lines. The arrows indicate the most dominant hadronic transitions. Single photon transitions, including $\Upsilon(nS) \to \gamma\eta_b(mS)$, $\Upsilon(nS) \to \gamma\chi_{bJ}(mP)$, and $\chi_{bJ}(nP) \to \gamma\Upsilon(mS)$, are omitted for clarity. For orientation, the location of the thresholds related to a pair of ground state open bottom mesons is indicated in the figure. Decays to open flavour final states are not shown in the figure. The transitions $\Upsilon(10753) \to \omega\chi_{b1}(1P), \omega\chi_{b2}(1P)$ have also been reported.

### WIDTH DETERMINATIONS OF THE $\Upsilon$ STATES

As is the case for the $J/\psi(1S)$ and $\psi(2S)$, the full widths of the $b\bar{b}$ states $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ are not directly measurable, since they are much narrower than the energy resolution of the $e^+e^-$ storage rings where these states are produced. The common indirect method to determine $\Gamma$ starts from

$$ \Gamma = \Gamma_{\ell\ell} / B_{\ell\ell}, \qquad (1) $$

where $\Gamma_{\ell\ell}$ is one leptonic partial width and $B_{\ell\ell}$ is the corresponding branching fraction ($\ell = e, \mu$, or $\tau$). One then assumes $e-\mu-\tau$ universality and uses

$$ \begin{gathered} \Gamma_{\ell\ell} = \Gamma_{ee} \\ B_{\ell\ell} = \text{average of } B_{ee}, B_{\mu\mu}, \text{ and } B_{\tau\tau}. \end{gathered} \qquad (2) $$

The electronic partial width $\Gamma_{ee}$ is also not directly measurable at $e^+e^-$ storage rings, only in the combination $\Gamma_{ee}\Gamma_{\text{had}}/\Gamma$, where $\Gamma_{\text{had}}$ is the hadronic partial width and

$$ \Gamma_{\text{had}} + 3\Gamma_{ee} = \Gamma. \qquad (3) $$

This combination is obtained experimentally from the energy-integrated hadronic cross section

$$ \begin{gathered} \int \sigma(e^+ e^- \to \Upsilon \to \text{hadrons}) dE \\ \text{resonance} \\ = \frac{6\pi^2 \Gamma_{ee} \Gamma_{\text{had}}}{M^2} C_r = \frac{6\pi^2 \Gamma_{ee}^{(0)} \Gamma_{\text{had}}}{M^2} \frac{C_r^{(0)}}{\Gamma}, \end{gathered} \qquad (4) $$

where $M$ is the $\Upsilon$ mass, and $C_r$ and $C_r^{(0)}$ are radiative correction factors. $C_r$ is used for obtaining $\Gamma_{ee}$ as defined in Eq. (1), and contains corrections from all orders of QED for describing $(b\bar{b}) \to e^+e^-$. The lowest order QED value $\Gamma_{ee}^{(0)}$, relevant for comparison with potential-model calculations, is defined by the lowest order QED graph (Born term) alone, and is about 7% lower than $\Gamma_{ee}$.

The Listings give experimental results on $B_{ee}$, $B_{\mu\mu}$, $B_{\tau\tau}$, and $\Gamma_{ee}\Gamma_{\text{had}}/\Gamma$. The entries of the last quantity have been re-evaluated consistently using the correction procedure of KURAEV 85 [1]. The partial width $\Gamma_{ee}$ is obtained from the average values for $\Gamma_{ee}\Gamma_{\text{had}}/\Gamma$ and $B_{\ell\ell}$ using

$$ \Gamma_{ee} = \frac{\Gamma_{ee}\Gamma_{\text{had}}}{\Gamma(1 - 3B_{\ell\ell})}. \qquad (5) $$

The total width $\Gamma$ is then obtained from Eq. (1). We do not list $\Gamma_{ee}$ and $\Gamma$ values of individual experiments. The $\Gamma_{ee}$ values in the Meson Summary Table are also those defined in Eq. (1).

¹BESSON 07 reports $[Γ(Γ(1S) → τ^+τ^-)/Γ_{total}] / [B(Γ(1S) → μ^+μ^-)] = 1.02 \pm 0.02 \pm 0.05$ which we multiply by our best value $B(Γ(1S) → μ^+μ^-) = (2.48 \pm 0.04) \times 10^{-2}$. Our first error is their experiment's error and our second error is the systematic error from using our best value.

$^2$BESSON 11 reports $(4.0 \pm 1.3 \pm 0.6) \times 10^{-5}$ from a measurement of $[\Gamma(\gamma(15S) \to \gamma f'_2(1525))/\Gamma_{\text{total}}] \times [B(f'_2(1525) \to K\bar{K})]$ assuming $B(f'_2(1525) \to K\bar{K}) = (88.8 \pm 3.1) \times 10^{-2}$, which we rescale to our best value $B(f'_2(1525) \to K\bar{K}) = (88.8 \pm 2.2) \times 10^{-2}$. Our first error is their experiment's error and our second error is the systematic error from using our best value. The result also assumes $B(K^0_S \to \pi^+\pi^-) = (69.20 \pm 0.05)\%$ and $B(f'_2(1525) \to K\bar{K}) = 4 B(f'_2(1525) \to K^0_S K^0_S)$.

$\chi_{b0}(1P)$

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

J needs confirmation.

Observed in radiative decay of the $\Upsilon(2S)$, therefore $C = +$. Branching ratio requires E1 transition, M1 is strongly disfavored, therefore $P = +$.
