Collaboration categories

The following list of major collaborations in HEP and related fields seeks to organize the collaborations by their primary focus. Where the focus could reasonably be included in more than one category, we have attempted to select the most meaningful. For example, although LHCb could be included in the "Hadron collider" category, its primary focus is the investigation of beauty sector physics and as such it has been included in the "Heavy Flavor Factory" category. However, this is not always possible and some collaborations have more than one category. This is very much a work in progress and we value your feedback.
