Online Particle Physics Information

Online resources are used in a diverse and expanding set of ways in particle physics. Many of these resources have become central to our collective work, and we provide a curated introduction to online resources as part of the Review of Particle Physics. That list is, by necessity, incomplete.

By contrast, this repository provides an expanded and regularly updated list of resources. It is meant to be inclusive and catalog all useful resources related to particle physics. The community is warmly invited to contribute in order to ensure a broad and up to date coverage of relevant resources.

⚠️ Inclusion of a resource on this list does neither imply endorsement by the PDG nor future inclusion in the curated introduction published in the Review of Particle Physics.

How to contribute

Any contributions are highly appreciated. There are several options to do so, depending on technical familiarity with the tools in use. You can either:

  • Edit this page directly and make a Pull Request. Note that this requires some familiarity with the Markdown format and the Github workflow, as well as an account on the platform.
  • Create an issue to let the maintainers know what needs to be changed. Note that this requires a Github account.
  • Send an email to the maintainers.

Table of contents

Particle Data Group (PDG) resources

  • Review of Particle Physics (RPP): A comprehensive report on the fields of particle physics and related areas of cosmology and astrophysics, including both review articles and a compilation/evaluation of data on particle properties. The review section includes articles, tables and plots on a wide variety of theoretical and experimental topics of interest to particle physicists and astrophysicists. The particle properties section provides tables of published measurements as well as the Particle Data Group's best values and limits for particle properties such as masses, widths, lifetimes, and branching fractions, as well as an extensive summary of searches for hypothetical particles. RPP is published as a large book every two years, with partial updates made available once each year on the web.

Particle physics information platform

  • INSPIRE: INSPIRE serves as a one-stop information platform for the particle physics community, comprising interlinked databases on literature, authors, jobs, seminars, conferences, institutions and experiments (each described in more detail below). Run in collaboration by CERN (which hosts INSPIRE), DESY, Fermilab, IHEP, IN2P3 and SLAC, it has been serving the scientific community for almost 50 years. Previously hosted at SLAC and known as SPIRES, it was the first website outside Europe and the first database on the web. Close interaction with the user community and with arXiv, ADS, HEPData, ORCID, PDG and publishers is the backbone of INSPIRE's evolution. Since 2020, it is running on a modernized platform that is continuously being improved.
