The ATLAS and CMS experiments at the Large Hadron Collider (LHC) have performed luminosity measurements with spectacular precision. A recent physics briefing from CMS complements earlier ATLAS results and shows that by combining multiple methods, both experiments have reached a precision better than 2%. For physics analyses—such as searches for new particles, rare processes or measurements of the properties of known particles—it is not only important for accelerators to increase luminosity, but also for physicists to understand it with the best possible precision.
