Standard Model

The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known subatomic particles. Developed throughout the mid to late 20th century, the current formulation was finalized in the mid 1970s upon...

, then missing information is retrieved from the online version CERN's Grey Book. The most specific information of the two is kept, e.g. if the SPIRES database lists December 2008, while the Grey Book lists 22 December 2008, the Grey Book entry is shown. When there is a conflict between the SPIRES database and the Grey Book, the SPIRES database information is listed, unless otherwise noted.
