Spell out in first use then use acronym for the CERN Courier

The SI unit of temperature. Spell out on first mention. Note the lower-case k (all SI units are lower case when spelled out); can be abbreviated to K (upper case) in subsequent mentions. Note that, although it is a measure of temperature, it is a standalone unit, not a type of degree, so never write "degrees kelvin" or "°K". The plural of kelvin is kelvins.

not "kilogramme"

K Long Experiment

Spell out in first use then use acronym for the CERN Courier

use hyphen

no italics

Liquid Argon

Use "past" rather than "last" in constructions such as "In the past few weeks...". If they were the last few weeks, that would imply that the end of the world is nigh, and you should probably be at home with your family rather than writing for a CERN website

Long-Baseline Neutrino Facility (in the US)

Long-Baseline Neutrino Oscillations (European collaboration)

Low-Energy Antiproton Ring

Large Hadron Collider

Initial capital letters. Always spell out first time (except in the CERN Courier), with abbreviation in brackets. Use the abbreviation thereafter.

Experiments at the Large Hadron Collider (LHC) suggest...

Beware of tautologies: Don't use "The LHC machine" or "The LHC accelerator", as this is equivalent to saying "The Large Hadron Collider accelerator...", which doesn't mean anything (the LHC doesn't accelerate accelerators).
