Updated PDG review articles are now available at
http://pdg.lbl.gov/ (see "Reviews, Tables, Plots").

More than half of the 118 review articles have been revised and a new review on neutrinos in cosmology was added, providing an up-to-date summary of results, experimental methods and mathematical tools of high-energy physics as well as related areas of cosmology. Further updates, especially those depending on the forthcoming 2018 Particle Listings, will be made prior to the publication of the 2018 edition of the Review of Particle Physics next summer.

We thank our 234 authors as well as our technical associates and the hundreds of members of the particle physics community who contributed to this update.

We always welcome your suggestions for improvements (please contact us at pdg@lbl.gov).

With kind regards,
Particle Data Group
