Errata for the 2020 Review of Particle Physics

P.A. Zyla et al. (Particle Data Group), Prog. Theor. Exp. Phys. 2020, 083C01 (2020).

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:
