Errata for the 2019 Review of Particle Physics

M. Tanabashi et al. (Particle Data Group), Phys. Rev. D 98, 030001 (2018) and 2019 update.

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 @

For errata in previous editions, please see:

Errata for the 2019 Edition:
Page 31 of the Particle Listing:
    Neutrino Mixing Listing     (page 31)
  • (July 18, 2019):
    $\Delta m^2_{32}$ "OUR FIT Assuming inverted ordering" value should read (units $10^{-3}$ eV$^2$):
    $\bf -2.55 \pm 0.04$  OUR FIT   Assuming inverted ordering
  • $\Delta m^2_{32}$ measurement of inverted mass ordering by ABE 18G should read (units $10^{-3}$ eV$^2$):
    $-2.507 \pm 0.070$    $^{3,4}$ABE  18G   T2K    inverted mass ordering, $\theta_{13}$ constrained
    4ABE 18G reports $\Delta m^2_{13} = (2.432 \pm 0.070) \times 10^{-3}$ eV$^2$ for inverted mass ordering. We convert to $\Delta m^2_{32}$ using PDG 18 value of $\Delta m^2_{21} = (7.53 \pm 0.18) \times 10^{-5}$ eV$^2$.

  • (July 18, 2019):
    $\Delta m^2_{32}$ inverted mass ordering entry should read:
    $\Delta m^2_{32} = (-2.55 \pm 0.04) \times 10^{-3}$ eV$^2$     (Inverted order)

  • (July 18, 2019):
    $\Delta m^2_{32}$ inverted mass ordering entry should read:
    $\Delta m^2_{32}$ (Inverted order)            $(-2.55 \pm 0.04) \times 10^{-3}$ eV$^2$
