NEWWorthy particle found – Xi-cc-plus-plus

To software engineers, this newly discovered — though predicted — particle sounds like an extension to the C++ programming language.  In actuality, the Xi-cc-plus-plus is a new kind of particle made up of two charm quarks.  Here’s the detailed (pdf) slide presentation.

It’s a heavy particle, and one of the most important findings about the Xi so far is that it helps to confirm the Standard Model.  In the long term, it might also help to refine our understanding of quantum chromodynamics.
