The Interactions Collaboration seeks to support the international science of particle physics and to set visible footprints for peaceful collaboration across all borders.

The Interactions.org website is designed to serve as central resource for information about particle physics, including press releases, articles, news, event listings and images. (It seems fitting that the World Wide Web, which came from particle physics, should have a role in supporting the science that created it.)

This website was developed and is jointly maintained by the Interactions Collaboration, whose members represent the world's particle physics laboratories in Europe, North America and Asia, with funding provided by science funding agencies of many nations.
