An abbreviated look at the alphabet soup of HEP-speak

by Pamela Zerbinos

If you’ve ever tried to speak with a member of the military, you know that comprehension is nearly impossible unless you’re familiar with its language. You probably also know that its language of acronyms sometimes seems...well, pointless. They don’t have cars, they have POVs—Privately Owned Vehicles.

While it’s true that acronyms in the HEP—er, High Energy Physics—community have a different purpose, it’s also true that the simple statement, “STAR is a QGP experiment at BNL’S RHIC,” will not draw even a flicker of understanding from the uninitiated. As the list of labs, agencies, accelerators, detectors and experiments grows ever longer, FERMINEWS decided it was time for an AHEP update.

Please note that although space in FERMINEWS is limited, an expanded acronym directory is available online at: www.fnal.gov/pub/inquiring/more/acronyms.html If we missed anything (and we did), please be sure to let us know.
