Σύνοψη	The Van der Meer scan is a precision measurement technique for determining the absolute luminosity at particle colliders by mechanically separating the colliding beams and measuring the collision rate as a function of beam separation. This fundamental calibration is essential for all cross-section measurements and physics analyses at the LHC and other hadron colliders.	Missing transverse energy (MET) is a powerful technique used in high-energy physics to infer the presence of invisible particles, primarily neutrinos, that escape a detector without leaving a trace. By measuring the imbalance of transverse momentum in the event, physicists can detect signatures of weakly interacting particles crucial for studying the Standard Model and searching for new physics beyond it.
