Errata for the 2018 Review of Particle Physics

M. Tanabashi et al. (Particle Data Group), Phys. Rev. D 98, 030001 (2018).

During the time between editions of the Review of Particle Physics and the Particle Physics Booklet, we often find a number of errata. We correct most errata on our WWW pages. If you should find errata that are not known to us, please send mail to pdg @ lbl.gov.

For errata in previous editions, please see:

Errata for the 2018 Edition:

Z-boson Particle Listing (page 3)

(November 16, 2018):
The value of the Z decay mode Γ₅ ( $\ell^+ \ell^- \ell^+ \ell^-$ ) fraction Γ₅/Γ should read: $(4.45 \pm 0.32) \times 10^{-6}$

Z-boson Particle Listing (page 7)

(November 16, 2018):
The header text under Γ( $\ell^+ \ell^- \ell^+ \ell^-$ )/Γ_total (Γ₅/Γ) should continue with:
The branching fractions in this node are given within the phase-space defined by the requirements that (i) the 4-lepton invariant mass is between 80 GeV and 100 GeV, and (ii) any opposite-sign same-flavor lepton pair has a di-lepton invariant mass larger than 4 GeV.
OUR AVERAGE value for the Z decay mode Γ( $\ell^+ \ell^- \ell^+ \ell^-$ )/Γ fraction should read: $4.45 \pm 0.32$
AAD 14N value for the Z decay mode Γ( $\ell^+ \ell^- \ell^+ \ell^-$ )/Γ fraction should read: $4.31 \pm 0.34 \pm 0.17$
CHATRCHYAN 12BN value for the Z decay mode Γ( $\ell^+ \ell^- \ell^+ \ell^-$ )/Γ fraction should read: $4.6^{+1.0}_{-0.9} \pm 0.2$ and have a footnote:
²CHATRCHYAN 12BN reports $(4.2^{+0.9}_{-0.8} \pm 0.2) \times 10^{-6}$ value. Their result (both central value and uncertainties) is scaled by 10% to account for the different phase-space definition used here (see RAINBOLT 18, arXiv:1805.05791 (2018)).

"Quark Model" review (page 202)

(August 13, 2019):
The charge of the d, s, and b quarks should be listed as $-1/3$ (in the first paragraph).
