NOTES

In this Summary Table:

When a quantity has “($S = ...$)” to its right, the error on the quantity has been enlarged by the “scale factor” $S$, defined as $S = \sqrt{\chi^2/(N-1)}$, where $N$ is the number of measurements used in calculating the quantity. We do this when $S > 1$, which often indicates that the measurements are inconsistent. When $S > 1.25$, we also show in the Particle Listings an ideogram of the measurements. For more about $S$, see the Introduction.

A decay momentum $p$ is given for each decay mode. For a 2-body decay, $p$ is the momentum of each decay product in the rest frame of the decaying particle. For a 3-or-more-body decay, $p$ is the largest momentum any of the products can have in this frame.

[a] See the review on “Form Factors for Radiative Pion and Kaon Decays” for definitions and details.

[b] Measurements of $\Gamma(e^+ \nu_e)/\Gamma(\mu^+ \nu_\mu)$ always include decays with $\gamma$'s, and measurements of $\Gamma(e^+ \nu_e \gamma)$ and $\Gamma(\mu^+ \nu_\mu \gamma)$ never include low-energy $\gamma$'s. Therefore, since no clean separation is possible, we consider the modes with $\gamma$'s to be subreactions of the modes without them, and let $[\Gamma(e^+ \nu_e) + \Gamma(\mu^+ \nu_\mu)]/\Gamma_{\text{total}} = 100\%$.

[c] See the $\pi^\pm$ Particle Listings for the energy limits used in this measurement; low-energy $\gamma$'s are not included.

[d] Derived from an analysis of neutrino-oscillation experiments.

[e] Forbidden by angular momentum conservation.

[f] C parity forbids this to occur as a single-photon process.

[g] As measured in $e^+ e^- \to \rho^0$.

[h] The $\omega\rho$ interference is then due to $\omega\rho$ mixing only, and is expected to be small. If $e\mu$ universality holds, $\Gamma(\rho^0 \to \mu^+\mu^-) = \Gamma(\rho^0 \to e^+e^-) \times 0.99785$.

[j] Our estimate. See the Particle Listings for details.

[J] See the “Note on $a_1(1260)$” in the $a_1(1260)$ Particle Listings in PDG 06, Journal of Physics **G33** 1 (2006).

[k] See also the $\omega(1650)$.

[l] See also the $\omega(1420)$.

[n] See the note in the $K^\pm$ Particle Listings.

[o] Neglecting photon channels. See, e.g., A. Pais and S.B. Treiman, Phys. Rev. **D12**, 2744 (1975).

[p] The definition of the slope parameters of the $K \to 3\pi$ Dalitz plot is as follows (see also “Note on Dalitz Plot Parameters for $K \to 3\pi$ Decays” in the $K^\pm$ Particle Listings):

$$|M|^2 = 1 + g(s_3 - s_0)/m_{\pi^+}^2 + \dots$$

[q] For more details and definitions of parameters see the Particle Listings.

[r] See the $K^\pm$ Particle Listings for the energy limits used in this measurement.

[s] Most of this radiative mode, the low-momentum $\gamma$ part, is also included in the parent mode listed without $\gamma$'s.

[t] Structure-dependent part.

[u] Direct-emission branching fraction.

[v] Violates angular-momentum conservation.

[x] Derived from measured values of $\phi_{+-}$, $\phi_{00}$, $|\eta|$, $|m_{K_L^0} - m_{K_S^0}|$, and $\tau_{K_S^0}$, as described in the introduction to “Tests of Conservation Laws.”

[y] The CP-violation parameters are defined as follows (see also “Note on CP Violation in $K_S \to 3\pi$” and “Note on CP Violation in $K_L^0$ Decay” in the Particle Listings):

$$\eta_{+-} = |\eta_{+-}| e^{i\phi_{+-}} = \frac{A(K_L^0 \to \pi^+ \pi^-)}{A(K_S^0 \to \pi^+ \pi^-)} = \epsilon + \epsilon'$$

$$\eta_{00} = |\eta_{00}| e^{i\phi_{00}} = \frac{A(K_L^0 \to \pi^0 \pi^0)}{A(K_S^0 \to \pi^0 \pi^0)} = \epsilon - 2\epsilon'$$

$$\delta = \frac{\Gamma(K_L^0 \to \pi^- \ell^+ \nu) - \Gamma(K_L^0 \to \pi^+ \ell^- \nu)}{\Gamma(K_L^0 \to \pi^- \ell^+ \nu) + \Gamma(K_L^0 \to \pi^+ \ell^- \nu)},$$

$$\mathrm{Im}(\eta_{+-0})^2 = \frac{\Gamma(K_S^0 \to \pi^+ \pi^- \pi^0)^{\mathrm{CP}} \mathrm{viol.}}{\Gamma(K_L^0 \to \pi^+ \pi^- \pi^0)},$$

$$\mathrm{Im}(\eta_{000})^2 = \frac{\Gamma(K_S^0 \to \pi^0 \pi^0 \pi^0)}{\Gamma(K_L^0 \to \pi^0 \pi^0 \pi^0)}.$$

where for the last two relations CPT is assumed valid, i.e., $\mathrm{Re}(\eta_{+-0}) \simeq 0$ and $\mathrm{Re}(\eta_{000}) \simeq 0$.

[z] See the $K_S^0$ Particle Listings for the energy limits used in this measurement.

[aa] The value is for the sum of the charge states or particle/antiparticle states indicated.

[bb] $\mathrm{Re}(\epsilon'/\epsilon) = \epsilon'/\epsilon$ to a very good approximation provided the phases satisfy CPT invariance.

[cc] This mode includes gammas from inner bremsstrahlung but not the direct emission mode $K_L^0 \to \pi^+ \pi^- \gamma$ (DE).

[dd] See the $K_L^0$ Particle Listings for the energy limits used in this measurement.

[ee] Allowed by higher-order electroweak interactions.

[ff] Violates CP in leading order. Test of direct CP violation since the indirect CP-violating and CP-conserving contributions are expected to be suppressed.

[gg] See our minireview under the $K_2(1770)$ in the 2004 edition of this Review.

[hh] This result applies to $Z^0 \to c\bar{c}$ decays only. Here $\ell^+$ is an average (not a sum) of $e^+$ and $\mu^+$ decays.

[ij] See the Particle Listings for the (complicated) definition of this quantity.

[jj] The branching fraction for this mode may differ from the sum of the submodes that contribute to it, due to interference effects. See the relevant papers in the Particle Listings.

[kk] These subfractions of the $K^- 2\pi^+$ mode are uncertain: see the Particle Listings.

[ll] See the listings under “$D \to K\pi\pi\pi$ partial wave analyses” and our 2008 Review (Physics Letters **B667** 1 (2008)) for measurements of submodes of this mode.

[nn] The unseen decay modes of the resonances are included.

[oo] This is not a test for the $\Delta C=1$ weak neutral current, but leads to the $\pi^+ \ell^+ \ell^-$ final state.

[pp] This mode is not a useful test for a $\Delta C=1$ weak neutral current because both quarks must change flavor in this decay.

[qq] In the 2010 Review, the values for these quantities were given using a measure of the asymmetry that was inconsistent with the usual definition.

[rr] This value is obtained by subtracting the branching fractions for 2-, 4- and 6-prongs from unity.

[ss] This is the sum of our $K^- 2\pi^+ \pi^-$, $K^- 2\pi^+ \pi^- \pi^0$, $K^0 2\pi^+ 2\pi^-$, $K^+ 2K^- \pi^+$, $2\pi^+ 2\pi^- \pi^0$, $K^+ K^- \pi^+ \pi^-$, and $K^+ K^- \pi^+ \pi^- \pi^0$, branching fractions.

[tt] This is the sum of our $K^- 3\pi^+ 2\pi^-$ and $3\pi^+ 3\pi^-$ branching fractions.

[uu] The branching fractions for the $K^- e^+ \nu_e$, $K^*(892)^- e^+ \nu_e$, $\pi^- e^+ \nu_e$, and $\rho^- e^+ \nu_e$ modes add up to $6.17 \pm 0.17\%$.

[vv] This is a doubly Cabibbo-suppressed mode.

[xx] Submodes of the $D^0 \to K_S^0 \pi^+ \pi^- \pi^0$ mode with a $K^*$ and/or $\rho$ were studied by COFFMAN 92B, but with only 140 events. With nothing new for 18 years, we refer to our 2008 edition, Physics Letters **B667** 1 (2008), for those results.

[yy] This branching fraction includes all the decay modes of the resonance in the final state.

[zz] This limit assumes the average of $B(D^0 \to K^- e^+ \nu_e)$ and $B(D^0 \to K^- \mu^+ \nu_\mu)$ for the $B(D^0 \to K^- \ell^+ \nu_\ell)$ value.

[aaa] This is the purely $e^+$ semileptonic branching fraction: the $e^+$ fraction from $\tau^+$ decays has been subtracted off. The sum of our (non-$\tau$) $e^+$ exclusive fractions — an $e^+ \nu_e$ with an $\eta$, $\eta'$, $\phi$, $K^0$, or $K^{*0}$ — is $5.99 \pm 0.31\%$.

[bbb] This fraction includes $\eta$ from $\eta'$ decays.

[ccc] The sum of our exclusive $\eta'$ fractions — $\eta' e^+ \nu_e$, $\eta' \mu^+ \nu_\mu$, $\eta' \pi^+$, $\eta' \rho^+$, and $\eta' K^+$ — is 11.8 $\pm$ 1.6%.

[ddd] This branching fraction includes all the decay modes of the final-state resonance.

[eee] A test for $u\bar{u}$ or $d\bar{d}$ content in the $D_s^+$. Neither Cabibbo-favored nor Cabibbo-suppressed decays can contribute, and $\omega - \phi$ mixing is an unlikely explanation for any fraction above about $2 \times 10^{-4}$.

[fff] We decouple the $D_s^+ \to \phi\pi^+$ branching fraction obtained from mass projections (and used to get some of the other branching fractions) from the $D_s^+ \to \phi\pi^+$, $\phi \to K^+ K^-$ branching fraction obtained from
the Dalitz-plot analysis of $D_s^+ \to K^+ K^- \pi^+$. That is, the ratio of these two branching fractions is not exactly the $\phi \to K^+ K^-$ branching fraction 0.491.

[ggg] This is the average of a model-independent and a K-matrix parametrization of the $\pi^+ \pi^- S$-wave and is a sum over several $f_0$ mesons.

[hhh] An $\ell$ indicates an e or a $\mu$ mode, not a sum over these modes.

[iii] An $CP(\pm 1)$ indicates the $CP=+1$ and $CP=-1$ eigenstates of the $D^0-\bar{D}^0$ system.

[iii] D denotes $D^0$ or $\bar{D}^0$.

[kkk] $D_{CP+}^* \to D^0 \pi^0$ decays into $D^0 \pi^0$ with the $D^0$ reconstructed in CP-even eigenstates $K^+ K^-$ and $\pi^+ \pi^-$.

[III] $\bar{D}^{**}$ represents an excited state with mass $2.2 < M < 2.8$ GeV/c$^2$.

[nnn] $\chi_{c1}(3872)^+$ is a hypothetical charged partner of the $\chi_{c1}(3872)$.

[ooo] $\Theta(1710)^{++}$ is a possible narrow pentaquark state and $G(2220)$ is a possible glueball resonance.

[ppp] $(\bar{\Lambda}_c^- P)_s$ denotes a low-mass enhancement near 3.35 GeV/c$^2$.

[qqq] Stands for the possible candidates of $K^*(1410)$, $K_0^*(1430)$ and $K_2^*(1430)$.

[rrr] $B^0$ and $B_s^0$ contributions not separated. Limit is on weighted average of the two decay rates.

[sss] This decay refers to the coherent sum of resonant and nonresonant $J^P = 0^+ K \pi$ components with $1.60 < m_{K\pi} < 2.15$ GeV/c$^2$.

[ttt] $X(214)$ is a hypothetical particle of mass 214 MeV/c$^2$ reported by the HyperCP experiment, Physical Review Letters **94** 021801 (2005)

[uuu] $\Theta(1540)^+$ denotes a possible narrow pentaquark state.

[vvv] $\psi_{DS}$ is a GeV-scale dark sector antibaryon (mass range 1–4 GeV/c$^2$).

[xxx] Here S and P are the hypothetical scalar and pseudoscalar particles with masses of 2.5 GeV/c$^2$ and 214.3 MeV/c$^2$, respectively.

[yyy] These values are model dependent.

[zzz] Here “anything” means at least one particle observed.

[aaaa] This is a $B(B^0 \to D^* \ell^+ \nu_\ell)$ value.

[bbaa] $D^{**}$ stands for the sum of the $D(1^1P_1)$, $D(1^3P_0)$, $D(1^3P_1)$, $D(1^3P_2)$, $D(2^1S_0)$, and $D(2^1S_1)$ resonances.

[ccaa] $D^*(\bar{D}^*)$ stands for the sum of $D^*\bar{D}^*$, $D^*\bar{D}$, $D\bar{D}^*$, and $D\bar{D}$.

[ddaa] $X(3915)$ denotes a near-threshold enhancement in the $\omega J/\psi$ mass spectrum.

[eeaa] Inclusive branching fractions have a multiplicity definition and can be greater than 100%.

[ffaa] $D_j$ represents an unresolved mixture of pseudoscalar and tensor $D^{**}(P$-wave) states.

[ggaa] Not a pure measurement. See note at head of $B_s^0$ Decay Modes.

[hhaa] For $E_\gamma > 100$ MeV.

[iiaa] $\Theta(1540)$ is a hypothetical pentaquark state of $1.54 \text{ GeV/c}^2$ mass and a width of less than 25 MeV/c$^2$.

[jjaa] Includes $p\bar{p}\pi^+\pi^-\gamma$ and excludes $p\bar{p}\eta, p\bar{p}\omega, p\bar{p}\eta'$.

[kkaa] For a narrow state A with mass less than 960 MeV.

[llaa] For a narrow scalar or pseudoscalar $A^0$ with mass 0.21–3.0 GeV.

[nnaa] For a dark photon U with mass between 100 and 2100 MeV.

[ooaa] For a narrow resonance in the range $2.2 < M(X) < 2.8$ GeV.

[ppaa] $J^{PC}$ known by production in $e^+ e^-$ via single photon annihilation. $l^G$ is not known; interpretation of this state as a single resonance is unclear because of the expectation of substantial threshold effects in this energy region.

[qqaa] $2m_\tau < M(\tau^+ \tau^-) < 9.2$ GeV

[rraa] $2 \text{ GeV} < m_{K^+ K^-} < 3 \text{ GeV}$

[ssaa] $X \bar{X}$ = vectors with $m < 3.1$ GeV

[ttaa] X and $\bar{X}$ = zero spin with $m < 4.5$ GeV

[uuua] $1.5 \text{ GeV} < m_X < 5.0 \text{ GeV}$

[vvaa] $201 \text{ MeV} < M(\mu^+ \mu^-) < 3565 \text{ MeV}$

[xxaa] $0.5 \text{ GeV} < m_X < 9.0 \text{ GeV}$, where $m_X$ is the invariant mass of the hadronic final state.

[yyaa] Spectroscopic labeling for these states is theoretical, pending experimental information.

[zzaa] $1.5 \text{ GeV} < m_X < 5.0 \text{ GeV}$

[aabb] $1.5 \text{ GeV} < m_X < 5.0 \text{ GeV}$

Baryon Summary Table

This short table gives the name, the quantum numbers (where known), and the status of baryons in the Review. Only the baryons with 3- or 4-star status are included in the Baryon Summary Table. Due to insufficient data or uncertain interpretation, the other entries in the table are not established baryons. The names with masses are of baryons that decay strongly. The spin-parity $J^P$ (when known) is given with each particle. For the strongly decaying particles, the $J^P$ values are considered to be part of the names.

Branching fractions marked with a footnote, e.g. [a], have been corrected for decay modes not observed in the experiments. For example, the sub-mode fraction $\Lambda_c^+ \rightarrow pK^*(892)^0$ seen in $\Lambda_c^+ \rightarrow pK^- \pi^+$ has been multiplied up to include $\bar{K}^*(892)^0 \rightarrow \bar{R}^0 \pi^0$ decays.

$$ \Lambda_c(2595)^+ $$

$$ I(J^P) = 0(\frac{1}{2}^-) $$

The spin-parity follows from the fact that Σ_c(2455)π decays, with little available phase space, are dominant. This assumes that $J^P = 1/2^+$ for the Σ_c(2455).

$$ \text{Mass } m = 2592.25 \pm 0.28 \text{ MeV} $$

$$ m - m_{\Lambda_c^+} = 305.79 \pm 0.24 \text{ MeV} $$

$$ \text{Full width } \Gamma = 2.6 \pm 0.6 \text{ MeV} $$

$\Lambda_c^+\pi\pi$ and its submode $\Sigma_c(2455)\pi$ — the latter just barely — are the only strong decays allowed to an excited $\Lambda_c^+$ having this mass; and the submode seems to dominate.

$$ \Lambda_c(2625)^+ $$

$$ I(J^P) = 0(\frac{3}{2}^-) $$

$J^P$ has not been measured; $\frac{3}{2}^-$ is the quark-model prediction.

$$ \text{Mass } m = 2628.00 \pm 0.15 \text{ MeV} $$

$$ m - m_{\Lambda_c^+} = 341.54 \pm 0.05 \text{ MeV} $$
