In quantum electrodynamics (QED), the quantum theory of electromagnetic interactions, the magnetic dipole moment of a particle acquires quantum corrections originating from interactions with virtual photons and other particles, often referred to as the anomalous magnetic moment of that particle.
In the same way that loud background noise does not allow us to listen to a conversation or appreciate a piece of music, so too the CMS detector needs a quiet environment to optimize data taking and analysis.
In this short series, we look at the different types of tests and steps needed for CMS to run at the precision the experiment requires.
It is compelling to picture large physics labs with lots of sparks and heavy levers that wake up big, important experiments with sparks and loud bangs.
