Errata for the 2025 Review of Particle Physics
S. Navas et al. (Particle Data Group), Phys. Rev. D 110, 030001 (2024) and 2025 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 @ lbl.gov.

For errata in previous editions, please see:

$\pi^0$ particle listing (web version page 6)
(August 22, 2025):
- "Linear Coefficient of $\pi^0$ Electromagnetic Form Factor" data block should begin with:
VALUE ($10^{-2}$)   EVTS    DOCUMENT ID   TECN   COMMENT
$3.32 \pm 0.29$   OUR AVERAGE
$3.0 \pm 1.0$ 0.4M   $^1$ADLARSON 17A   SPEC    $\gamma p \to \pi^0 p$, $\pi^0 \to e^+ e^- \gamma$
(...)

$^1$ADLARSON 17A use the A2 tagged photon facility at the Mainz Microtron, MAMI to meaasure $\pi^0$ Dalitz decay. The error is the total estimated experimental uncertainty.
