Capital C. The "at" sign in the name can sometimes cause problems with Drupal text formats. To get around this, whenever Collide @ CERN appears in text, separate the @ from the text with spaces.

Collide @ CERN is a three-year artist’s residency programme at CERN.

Use "collision" to refer to the exact point in time and space at which particles collide.

An "event" is a snapshot of what happens after a collision; an event is picked up by the detector: particles decay and their decay products form tracks or deposit energy in the detector.

Event displays from the detectors show the collision point in the middle – everything around it makes up the event.

Don't use it in web texts. Use seminar instead.

Don’t use an Oxford comma in straightforward lists with no risk of ambiguity: The good, the bad and the ugly, NOT the good, the bad, and the ugly.

Do use it in lists of long phrases each containing their own punctuation, or in cases in which it is essential to convey the correct meaning: I dedicate this book to my parents, J.K. Rowling, and Martin Amis not I dedicate this book to my parents, J.K. Rowling and Martin Amis.

If possible try to remove the need to use an Oxford comma in your writing.

Contractions such as “there’s” “they’re”, “didn’t”, “he’ll” and “she’d” do not automatically make a story more accessible. Contractions can appear annoyingly chatty, and can be imprecise too (“it’s” can stand for “it is” or “it has”) and so detract from clarity. If anything, contractions make a story harder to understand, especially if there are several of them in the same sentence.

no hyphen, except in the CERN Courier
